DynamicPopulateExtender Problem
---------------------------------------------

at that time, i used the method reside on the .aspx page decorated with
[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
like this way: http://www.asp.net/AJAX/AjaxControlToolkit/Samples/DynamicPopulate/DynamicPopulate.aspx

After that, i created one method on .asmx page with decorated
[WebMethod]
like this way:

http://www.google.com/url?sa=t&ct=res&cd=1&url=http%3A%2F%2Fdownload.microsoft.com%2Fdownload%2Fb%2F6%2Fa%2Fb6ae89ee-df69-4c87-9bfb-ad1eb2b23373%2Fdynamicpopulate0CS.pdf&ei=9HCDSM63EoOY6gPA4LzIAg&usg=AFQjCNEQIIr4KgXEbLrP7J9Qfki8qWBLPw&sig2=4zaheld50bcu1_jJvHOHzA

For me it works

Thanks,

For updating the elements I hope the below code will work

Assign the values to individual elements in the panel
HtmlTextWriter htw = new HtmlTextWriter(sw);
<panel>.RenderControl(htw);
htw.Flush();
return sw.ToString();

this return string I can output is as the innerHTML of the div in the tab. I have previously used it for rendering gridview contol.

If you want to update an entire tab with controls, why not use a server side event?

Put your tabcontrol in an update panel and populate the tab on the serverside OnActiveTabChanged event.

You cannot use the DataGrid and Label in combination with dynamic populate control, because there is no Page context in a webservice call.

There is an example website with the AjaxControlToolkit that describes all the stuff you need to do to get it to work, have you tried looking there?

I have little expierence with the control, I just know it is there for this purpose.

Thanks Maddus. I tried but got an error "Web Service call failed: 500" Please see the code below

added a button and the DynamicPopulateExtender control in my aspx file

asp:Button runat="Server" ID="btnSearch" Text=" Search " OnClientClick="updateDateValues();return false;" />

ajaxToolkit:DynamicPopulateExtender ID="dpTabGeneral" BehaviorID="dpTabGeneral" runat="server" TargetControlID="updPnlGeneral" ClearContentsDuringUpdate="true" ServiceMethod="popTabGeneral" UpdatingCssClass="modalBackground" />

In the JS file I have

function

updTabGeneral() {
   var behavior = $find('dpTabGeneral');
   if (behavior) {
      behavior.populate();
   }
}
function updateDateValues(){
   updTabGeneral();
}

In the CS file I have

public void popTabGeneral(string contextKey)
{
   DataSet ds = <get value from database>;
   lblCustRole.Text = value from ds;
   //similarly populate other elements incl gridview
}

Please help

Take a look at the DynamicPopulateExtender. I think that it fit's your scenario best.
