How do I recognize dynamic buttons as triggers for updating updatepanels?

I have two updatepanels on a page each with a datagrid inside the panels. I need updatepanel B to update it's datagrid when a LinkButton is clicked inside udatepanel A's datagrid. The linkbuttons are dynamically generated for each row of the datagrid.

Thanks

Stripped Down Example:

<asp:UpdatePanel id="pnl1" runat="server">
<ContentTemplate>
<asp:datagrid id="dgA" runat="server" > ... <asp:LinkButton ID="lbtnSelect" CommandArgument=' ... ' runat="server">...</asp:LinkButton> ... </asp:datagrid>
</ContentTemplate>
</asp:UpdatePanel>

<!-- Next Panel -->

<asp:UpdatePanel id="pnl2" runat="server">
<ContentTemplate>
<asp:datagrid id="dgB" runat="server" > ... </asp:datagrid>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="lbtnSelect" EventName=" ... "/>
</Triggers>
</asp:UpdatePanel>

Unless I misread your post, I think that all you need to do is add the following line inside of your event handler for the link buttons (lbtnSelect_Click, or similar):

pnl2.update();

This should update your pnl1 because the linkbutton's click event fired inside of pnl1, andprogrammatically updating pnl2 with pnl2.update() should take care of updating the other datagrid (dgB). You can get rid of the <Triggers> definition too.

How can Rating Control triggers a event where i click the CurrentRating?

a Rating Control Question

when i clicked the star what was not CurrentRating, it triggered a Changed event,
but i clicked the CurrentRating star, nonthing happened.

now, i'm writting a project. it's needed to show a rating of a item, and allow users to rate it.
i encountered a trouble, user can't rate by the same rating

for example, the current rating is 3, a user wants to rate by 3, but no event been triggered, because Rating control only has Changed event.
if rating were not changed, no event occured.

how can i resolve the problem? write a new control class to extend Rating? or other easier methods?

hi, can someone help me ?

How can I utilize AjaxControlToolkit:CalendarExtender inside my Gridview during edit mode?

Hello guys,

I have a Gridview control that has StartDate, EndDate field columns. In edit mode, when I clicked the StartDate or EndDate textbox to change the date, I need the calendarExtender popup, so I can select any particular date.

I tried this code in my ASPX page code behind, but still didn't work. Here is the code snippet:

...
TextBox txtStartDate = (TextBox)row.FindControl("txtStartDate");
AjaxControlToolkit.CalendarExtender calExtender =new AjaxControlToolkit.CalendarExtender();
calExtender.Format ="MM/d/yyyy";
calExtender.CssClass ="ajax__calendar";
calExtender.TargetControlID ="txtStartDate";
calExtender.DataBind();

TextBox txtEndDate = (TextBox)row.FindControl("txtEndDate");
AjaxControlToolkit.CalendarExtender calExtender2 =new AjaxControlToolkit.CalendarExtender();
calExtender2.Format ="MM/d/yyyy";
calExtender2.CssClass ="ajax__calendar";
calExtender2.TargetControlID ="txtEndDate";
calExtender2.DataBind();
...

Is there any step procedures, source code, or reference example, etc. I can use to accomplish this task? I greatly appreciate for any help to solve this problem. Thanks.

Why not convert your bound column to a item template column and drop the CalendarExtender Control directly inside the GridView?

or just use something similar toGreg Benoit's resusable calendar solution

I use this all over my site and i only have 1 calendar extender in the entire app. You can easily attach the extender on-the-fly using his example

I'll try to implement it on my Gridview control. Thanks for your suggestion.
