How can I use a email regular expression in Ajax Toolkit

Hi I am developing an application using the validations of AJAX Toolkit. In one screen i make the user input the email address. I want to have a regular expression which will validate the input done by user. How can i add a regular expression in Ajax Toolkit.

Early response will be appreciated.

drag a regularexpression validator on your form & set its controltovalidate property and regularexpression property. The client side validations will trigger before the partial postback.

See the last bullet on this page:http://blogs.visoftinc.com/archive/2007/09/23/asp.net-ajax--updatepanel-not-working--common-problems.aspx about using validators with an UpdatePanel (assuming this is what you mean by the "Ajax Toolkit")

To use the the ValidatorCallout with your RegularExpressionValidator, seehttp://www.asp.net/AJAX/AjaxControlToolkit/Samples/ValidatorCallout/ValidatorCallout.aspx

You have to set ValidationExpression Property of RegularExpressionValidator.control

how can i make ajax work this way?

on my form, clicking on the navigation items on the left of screen will filter/refresh the gridview on the right hand side,

how can i achieve this using Ajax and not let the navigation items to reload themselves? (only the gridview refreshes)

Just make sure you only wrap the content you want to be dynamic with theUpdatePanel. That should be all you need. Start there and let us know if you're not getting what you want.

Thanks flanakin, in my applicaton, the dropdownlist has already been placed outside of UpdatePanel. the whole page reloads because the dropdownlist is "autopostback".

I found 3 lines of code that helped me to stop the whole page reload:

<Triggers>

<asp:AsyncPostBackTriggerControlID="DropDownList1"EventName="SelectedIndexChanged"/></Triggers>

I put the code inside the code of UpdatePanel, it worked, This can also be achieved by setting "Triggers" property of the UpdatePanel in design view
