How do I use external scripts in controls, with brittle-old-atlas?

Hi, I realise Atlas is still in preview, but unfortunately it doesnt stop customer's demands :(

I've a server control that will not work with Atlas. I've whittled the problem down to this external script line.

<script type='text/javascript'src='/AtlasWebSite1/WebResource.axd?d=Q25Q6XUyjAkwUhmccPLXSM0tUH1gG8pvBlJoQRJbY9aaHhPMSqiC1p5xfcybhbNW0&t=632864860774426576'></script
This is registered with Page.ClientScriptBlock (I know ASP.NET2 hasdifferent syntax, but my control needs to support .NET1.x so the codeis easier to leave as is - it works with ASP.NET2 just fine).

Here's the kicker, the embedded script referred to above is just a small JS file with everything commented out.

If I don't register the script, the page works, if I do register thescript, then my simple little page with an UpdatePanel fails to updatewhen a postback happens. Please refer to my earlier post on thesame problem for the actual aspx pagehttp://forums.asp.net/thread/1318847.aspx

The script line above appears in the rendered code in the correct place

<form name="form1" method="post" action="default.aspx" id="form1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTUxNzQwOTU4NGRkq48mV8BeUZdYRTUdUDPaQYzABY0=" />
</div
<script type="text/javascript">
<!--
var theForm = document.forms['form1'];
if (!theForm) {
theForm = document.form1;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}
// -->
</script

Any and all help gratefully received, thanks!

JimHas nobody else experienced this?

I've reproduced it with a simple control that does nothing more than register an embedded script (which is empty).

Thanks

Turns out it works OK in Firefox, just not in IE6. Kind of ironic.

Please somebody, put me out of my misery!

Nevermind, I've had to work around it, looks like a bug in Atlas :(

How do I UnitTest My Atlas component

Hi,

Can anyone guide me how I can unit test my atlas component. Here is the scenario
I have existing app which is using javascript ...now i was thinking about removing it
and implement atlas functionality. However this gives me opportunity to write test
cases. Can someone tell me if MSTS has inbuilt functionality for this or which other
way i can test my component built in atlas. Will Nunitasp or Nunit work?

Thank you

VSTS does not have built-in support for JavaScript. Neither does NUnit. You might be able to use NUnitAsp, but I would recommend JsUnit:http://www.edwardh.com/jsunit/

How do I tell which version of atlas Im running?

Hi, Im running an old version of Atlas, and I need to upgrade it to I guess the latest ajax.net right?

There are instructions on hompage for upgrading from "ctp" to "rc" or from "beta 2" to "rc". How do I tell what version I have and what version do I want to upgrade to?

Also, with this upgrade, with that also upgrade my atlas control toolkit?

Thanks, sorry so noobish, I just want to make sure i upgrade this right the first time, thanks.

Thanks, sorry so noobish, I just want to make sure i upgrade this right the first time, thanks.

The web.config file should be upgraded automatically when installing the new version. The old controls on toolkit need to be remove manually and the new controls need to be added manually. Hope that helps.

and will my old controls still work?

If I completely backup my existing project before upgrade, and this upgrade breaks my projects, can I just reinstall the old version again to restore?

I never had any problem with its upgrade so I wouldn't know if you can downgrade it or not. Your old controls need to be removed. They will not work due to the changes in web.config file.

How do I manually trigger a nextpage for the data navigator?

So I'm already familiar with

http://atlas.asp.net/docs/util/srcview.aspx?path=~/atlas/samples/data/DataNavigator.src

and I can get it to work with buttons

but lets say we replaced those buttons with anchor tags instead?

oh wait I just figured it out. You don't do anything just chaging those elements to anchors and leaving them labeled as buttons in the XML markup causes the same behavior.. That's cool. why is that? My guess is because anchor and button both have the exact same onclick event which is the event that is raised.

OK well than for academic reasons how would I invoke a next page on a DataNavigator without a button like lets say from a hyperlink object or from javascript code?

I tried creating a datanavigator object in javascript code

var

pageNavigator =new Sys.UI.Data.DataNavigator($("pageNavigator"));

pageNavigator.initialize();

alert(pageNavigator.get_dataView());

pageNavigator.onBubbleEvent(

null,"nextpage");

but that didn't work at all.

All the DataNavigator control does is increment the pageIndex property on its associated DataView component. Knowing that, you can easily do the same thing:

var dataView = $object('dataView');
dataView.set_pageIndex(dataView.get_pageIndex() + 1);

Hope that helps.

How do I make atlas pages pass W3C Validator?

Whenever I try to validate asp.net pages with atlas controls on the W3C Validation Service I get errors like this:

ErrorLine 506 column 19:there is no attribute "xmlns:script".
<page xmlns:script="http://schemas.microsoft.com/xml-script/2005" xmlns:atlascon

and

ErrorLine 506 column 93:there is no attribute "xmlns:atlascontrolextender".
...ipt/2005" xmlns:atlascontrolextender="atlascontrolextender" xmlns:atlascontro

I was really surprised this didn't work especially when it says at the top that it has imported these namespaces:

http://schemas.microsoft.com/xml-script/2005atlascontrolextenderatlascontroltoolkit

Is there something that I'm supposed to do to make this work that I'm missing?

I'm not an expert, but Ithink that if you were to convert all XML script tags inside the (XHTML) <script> tag to be prefixed with script:, it would work. E.g.:

<script:page xmlns:script="http://schemas.microsoft.com/xml-script/2005"...>
<script:otherTag>
</script:otherTag>
</script:page>

How do do this, though, is anyone's guess :(.

How do I know the load?

I have my web pages that are using web services via atlas technology. when page loads users can click on the links but get error because page has not been loaded yet. How do I know that page loaded on atlas? How do I know that procies are created? can someone provide me some working javascript or what ever is possible to detect it?

thanks and greately appreaciated

Hi,

just hook up the load event raised by the global Sys.Application instance. Here's the code to add to your page:

<script type="text/javascript">
<!--
function onLoad() {
// Put your Atlas stuff here.
}
//-->
</script>
<script type="text/xml-script">
<page>
<components>
<application load="onLoad" />
</components>
</page>
</script>

The above code will call the onLoad function (it's a javascript function that you have to define) when all the framework stuff is initialized.

How do I intsall the Atlas Control Toolkit?

Can someone please direct me on where I can find documentation or webpage on how to install the Atalas Control Toolkit?

hello.

well, you just download it and then add the dll to your bin's folder.

You can find it here:

http://ajax.asp.net/default.aspx?tabid=47&subtabid=477

How do I integrate 3 party javascripts into Atlas the right way??

I found a great modalpopup window javascript and would like to use it with Atlas.

I guess I could add the script to the Atlas Scriptlibrary and than add it to my we page like this:

<atlas:ScriptManager runat="server" ID="UpdatePanel2"

EnableScriptComponents="True"EnablePartialRendering="True">

<Scripts>

<atlas:ScriptReference Path="~/ScriptLibrary/MyScript.js" />

</Scripts>

</atlas:ScriptManger>

Does this code make the javascript in on my webpage available?

Or I can do it like this:

<script src="http://pics.10026.com/?src=scripts/prototype.js" type="text/javascript"></script>

<script src="http://pics.10026.com/?src=scripts/lightbox.js" type="text/javascript"></ script>

But I would like to work within Atlas. Which brings me to my second question? This javascript uses the prototype.js framework. When I use Atlas do I still need the prototype.js or does Atlas replace those functions?

What I want to know is how do I integrate 3 party javascripts into Atlas the right way?

hello.

you can do it either way...normally, i use the <script> element...

How do I get started with AJAX.Net?

Hi All,

I'm a seasoned asp.net developer but have not yet ventured into atlas et al.

I prefer books, but will take whatever I can get if it's good and will get me going.

Any recommendations?

Thx in advance.

try here first

then learn from sample and doc

I find the materials online display features and implementations but are lacking architectural depth, and am seeking more comprehensive resources.

By architectural depth, I mean that I cannot watch a video and the code something right away. I'm left guessing...

Any additional recommendations?

How do I extend an Atlas extender?

Let's say I create my own Atlas Control Extender. For example, I create an extender called MyHoverExtender. But instead of extending Control or WebControl, I want to extend the HoverMenuExtender. But when I change it to use that, I get this error:

error BC32044: Type argument 'SearchResultItem.MyHoverExtenderProperties' does not inherit from or implement the constraint type 'Microsoft.AtlasControlExtender.TargetControlPropertiesBase(Of AtlasControlToolkit.HoverMenuExtender)'.

Can anyone help me with this error?

Thanks

The extender class and the properties class have to travel in pairs. So if you derive from the extender, you need to also do so from the properties class. I think if you just have your MyHoverExtenderProperties class inherit from HoverMenuProperties you should be OK.

So here's what I've got right now:

-----------------

MyHoverExtenderDesigner.vb:

Class MyHoverExtenderDesigner
Inherits Microsoft.AtlasControlExtender.Design.ExtenderControlBaseDesigner(Of MyHoverExtenderProperties, AtlasControlToolkit.HoverMenuExtender)
End Class

Produces this error:

error BC32044: Type argument 'SearchResultItem.MyHoverExtenderProperties' does not inherit from or implement the constraint type 'Microsoft.AtlasControlExtender.TargetControlPropertiesBase(Of AtlasControlToolkit.HoverMenuExtender)'.

-----------------

MyHoverExtenderExtender.vb:

<Assembly: System.Web.UI.WebResource("SearchResultItem.MyHoverExtenderBehavior.js", "text/javascript")>

<System.ComponentModel.Designer(GetType(MyHoverExtenderDesigner))> _
<Microsoft.AtlasControlExtender.ClientScriptResource("MyHoverExtender", "MyHoverExtenderBehavior", "SearchResultItem.MyHoverExtenderBehavior.js")> _
Public Class MyHoverExtenderExtender
Inherits Microsoft.AtlasControlExtender.ExtenderControlBase(Of MyHoverExtenderProperties, AtlasControlToolkit.HoverMenuExtender)
End Class

Produces this error:

error BC32044: Type argument 'SearchResultItem.MyHoverExtenderProperties' does not inherit from or implement the constraint type 'Microsoft.AtlasControlExtender.TargetControlPropertiesBase(Of AtlasControlToolkit.HoverMenuExtender)'.

-----------------

MyHoverExtenderProperties.vb

<System.ComponentModel.DefaultProperty("MyProperty")> _
Public Class MyHoverExtenderProperties
Inherits Microsoft.AtlasControlExtender.TargetControlPropertiesBase(Of AtlasControlToolkit.HoverMenuProperties)

Public Property MyProperty() As String
Get
Return GetPropertyStringValue("MyProperty")
End Get
Set(ByVal value As String)
SetPropertyStringValue("MyProperty", value)
End Set
End Property

End Class

This file builds without any errors as far as I can tell.

Oh, sorry, just find my problem.

The MyHoverExtenderProperties class was declared thusly:

Public Class MyHoverExtenderProperties
Inherits Microsoft.AtlasControlExtender.TargetControlPropertiesBase(Of AtlasControlToolkit.HoverMenuProperties)

But it should be declared:

Public Class MyHoverExtenderProperties
Inherits Microsoft.AtlasControlExtender.TargetControlPropertiesBase(Of AtlasControlToolkit.HoverMenuExtender)

That's closer. Does that work?

I think you actually want:

public class MyHoverExtender inherits HoverMenuExtender

public class MyHoverExtenderProperties inherits HoverMenuProperties

What you have above says that you'll be extending controls of type HoverMenuExtender, which I don't think you want.

Yeah, I think you're right. I'm in the process of confusing myself today between wanting to extend my own custom control using a modified version of the hover extender. I think I've almost got my head around it all.

:) Okay if you want more help confusing yourself, just let us know and we'll be glad to lend a hand.

Seriously, our refresh should help with this - I'm concerned you may run into some issues getting the right scripts to load as is. I haven't tried what you're doing so do let us know.

How do I extend a DataGrid/DataList for ATLAS behavior?

I have two inherited DataGrid and DataList classes that render a paged grid and list with some enhanced behaviors (better pagers and retreiving only items that are shown with NHibernate). I would like paging not to refresh the page.

It's easy with an UpdatePanel: add a panel, add an event OnDataBinding( ) and Update the panel. For my project (www.foodcandy.com) this means updating a hundred grids and lists.

So instead I would like to build the panel behavior into the actual DataGrid and DataList and have all my grids behave this way. The first easy thing is to add a panel property and tell the grid/list that it's inside an update panel. But I still have to modify a 100 pages to add the update panels.

How do I do something like that?

Thx
dB.

hello.

maybe building a usercontrol will be the faster way to get what you want...though i still think that i'd add the panel to all the pages..

I doubt it will be faster Luis - this is a datagrid, I would need to expose all the methods for various properties like PagerStyle and I am not even sure what to do with ItemTemplates. No?

hello.

well, i was thinking in adding a property to the usercontrol that lets you get a reference to the datagrid.

Luis Abreu:

well, i was thinking in adding a property to the usercontrol that lets you get a reference to the datagrid.

I haven't tried this, but can you nest this in the aspx pages by having MyUserControl expose the DataGrid member?

<MyUserControl>
<DataGrid>
<TemplateColumn ... />
</DataGrid>
<MyUserControl>

how do I develop an Atlas application?

Hi

I have been developing asp.net applications for a couple of years now and am trying to get my head around this atlas/ajax thing.

If I was to build an application of say 20 .aspx pages I would know exactly how to go about it but I am a bit stumped on how to start an Atlas enabled one that is maintainable in a logical manner.

Instead of seperate aspx pages, do I use a user control for each "page" instead and make ajax call backs from a single page?

I can follow the examples on the Atlas website but they tend to contain only a little bit of functionality on each page - is this the way that most people are using it?

Are there any online documents that describe best practices for architecting a decent sized application using Atlas?

Any help or direction pointing would be appreciated.

cheers

Yes, I'm still organizing my sites into logical pages with atlas being used to update sections of the page dynamically, but the same principles hold true with normal asp.net functionality. You wouldn't create a site with only one asp.net page and try to handle all your functionality within just that one page with showing/hiding placeholders and event handlers for all your events. (At least I wouldn't!) I don't think you'd do the same with atlas. At some point you're going to want to load a new page, and that involves communicating with the server. I think there's only so much you want the client/surfer's PC doing - some things are better/safer when handled on the server and the resulting html returned to the client browser. It depends on your needs and what you're trying to do. That's just my .02.

(Plus you can't have an updatepanel inside a template, like a repeateritem, (yet :), so that really limits alot of what you can do anyway within just one aspx page)

i have worked on application which involves team management and it was round abt 20 pags app. We have put ajax on main pages like tasks list, billing pages and hours tracking page. Rest of the site, which involves add,edit ,delete such as for users ,projects etc ; we have used normal post back.

Dont design ur web app like a win app, with one form and many user controls. This will cause head ache in future.

ok thanks for that guys.

that actually helps a lot - I was getting myself confused with what was "possible". It looks like performance is still king in asp.net

How do I collapse Collapsible Panel

I'm trying to write SlideMenu very similar to the way that the SlideMenu onwww.obout.com works using the Atlas Collapsible panel extender.

Is there a way that I can programatically collapse the panel. basically if i have 5 panels controls collapsible if one if opened i want the other four to close. Can anyone tell me how i can do this in code behind or client side.

The newest release of the toolkit contains an Accordian control (sorry we don't have a sample page posted yet) that does exactly what you're looking for. Check it out by downloading from:

how do i autocomplete in ajax?

hi every1 i just upgraded from atlas to ajax 2.0

it wasnt to hard but i have a problem i used the <atlas:autocomplete

tag in atlas

but it wasnt like the other tags i cant just cahnge the atlas to asp:

cause it dosnt have it

how can i do it then?

any1 know?

plz help tnx a lot

Hi, you can easily implement auto completion in ajax using AJAX AutocompleteExtender, the sample code is shown below.

.aspx page

<asp:TextBox ID="txt_search_city" Width="130px" runat="server">

<cc1:AutoCompleteExtender ID="AutoCompleteExtender2" runat="server" TargetControlID="txt_search_city"
ServiceMethod="GetCompletionListWithContext" UseContextKey="true" MinimumPrefixLength="2"
EnableCaching="false" CompletionSetCount="20" CompletionInterval="2000" FirstRowSelected="true"
DelimiterCharacters=";," />

And in Code Behind - aspx.vb

<System.Web.Services.WebMethod()> _
<System.Web.Script.Services.ScriptMethod()> _
Public Shared Function GetCompletionListWithContext(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String()
If Not contextKey = Nothing Then
Return "this is a total of fifteen words that will be returned when we use context".Split(" ")
End If
If count = 0 Then
count = 20
End If
Dim items As New System.Collections.Generic.List(Of String)
'get data from database
Dim _loc As New Locations
Dim str As String
Dim ds As DataSet = _loc.Load_Cities(prefixText, count)
If ds.Tables(0).Rows.Count > 0 Then
Dim i As Integer
For i = 0 To count - 1
str = ds.Tables(0).Rows(i).Item("city").ToString()
items.Add(str)
Next
End If
Return items.ToArray()
End Function

This will help you implementing auto completion in ASP.NET 2.0 using AJAX Toolkit

hi tnx for the reply

but can you maybe tell me how do i do it in c#?

and what are these two?

<System.Web.Services.WebMethod()> _
<System.Web.Script.Services.ScriptMethod()>

where do i put stuff like that?

please help

tnx

Hi,

AJAX Toolkit Autocomplete Extender use Webservice Method for fetching records and display in auto popup list, when user type some text in textbox. therefore you must create web method with same definition as describe in ajax autocomplete documentation.

If you want not to create separate webservice page, instead of it define method in normal page code behind, then you must first, import the following namespace.

using System.Web.Services;

using System.Web.Script.Services;

then in code create a method as shown below.

[WebMethod]
public string[] GetCompletionList(string prefixText, int count)
{

'// rest define in another post

}

Thanks.

How Do I add Atlas to a Current project?

All,I am trying to add atlas to a current project so I can use some things from the toolkit. I tried dragging in the collapsible panel from the toolbar, but what else should I do to make it work?

Karls

There is some stuff you have to add to your web.config. Search Google harder, it is out there, I just did this recently and had to find it. I believe it was on Scott's blog or the Microsoft web site. Don't get confused about how to add Atlas to Visual Studio (toolkit) from Adding Atlas to your project.

How do I add ATLAS feature to an existing ASP.NET 2.0 Web Application?

Hi all,

Can some one provide me the steps needed to add ATLAS features to an existing ASP.NET 2.0 Web Application?

I saw the video "Developing ASP.NET 2.0 Applications using "Atlas"" byScott Guthriewhere he explained how to add ATLAS features to the To-do application. But to start with, he created anATLAS WEBSITE PROJECTand started modifying it.

I see that the config file is very important for ATLAS to function correctly. What other dependency is there? How do I create an ATLAS enabled "Web application"?

Most importantly, if i have an ASP.NET 2.0 Web Application, how do i add ATLAS features to it?

Thankx in advance

Jacob

from other thread:

ScottGu:

The easiest approach might be to create a newweb-site using the Atlas template, and then copy the resultingAtlas.dll into the \bin directory of your existing application andintegrate the web.config file changes in as well. Then you should begood to go.

Hope this helps,

Scott

hello.

well, you must:

1. add the atlas dll to the bin folder and
2. add the necessary entries to the web.config file

note that you can get the dll from the installation folder (normally, program files\microsoft asp.ent\atlas\v...\atlas and you can also see the necessary web.config entries by opening the web.config file that exists on that dir.

Hi luis,

Thankx for the information. However, this i what is had figured too. I had tried this earlier but some how, it did not seem to be working.

I was looking to see if some one has already done this, and can specify the detailed steps, including the web.config changes etc..

did you ever try to do this? Were u able to make it work? I wanted to use the new 'atlas' control toolkit. Do u think it would be easy to integrate this to an existing web application?

What difference are there between an ASP.NET 2.0 Web Application and ATLAS Website Project provided by the visual studio? Is that only the web.config which differs?

thankx

How do I acces profiles from a web service called from Atlas?

I have a web service that is called by a page that employs Atlas. I was wondering if there is a way to access the profile of the user from the webservice?

I'm trying to use HttpContext.Current.Profile.GetPropertyValue() but it's returning empty data. Is there anything that I have to set up?

Hi Zephyr,

Can you check to see whether the User.Identity.Name property is available in your web-service? This will indicate whether the user is logged in when the web-service is called. My guess is that they aren't - which is why the Profiloe is coming back null.

Thanks,

Scott

How do I "replace" the ACT controls in my application?

Hi,

Nope. Just make sure the DLLs are replaced and everything should be fine.

Thank you.

How can to get a Dataset from client in Atlas?

When I return a dataset in server and get result in client, there's always a error like this

"System.InvalidOperationException - a circular reference was detected while serializing an object of type 'System.Globalization.CultureInfo'".

Does Atlas not support get a dataset ?

Add the Preview verison to work with dataset, datatables etc.

Amit
Are you referring to the May Futures and the Microsoft.Web.Preview.dll?
If so, where is the support in the May Futures for Client access to datasets/datatables?
I looked at the documentation for the Futures and didn't see it.
Thanks for your help...
