Problems with RequiredFieldValidators within an Ajax loaded ASCX

[Boris]

I can see there are some problems with the validators but so far I haven't found exactly my scenario.
I've based my code on the example  http://demos.telerik.com/aspnet-ajax/ajax/examples/common/loadingusercontrols/defaultcs.aspx

I have a FormTemplate popup within a RadGrid.  On that template I have one RadAjaxPanel containing a RadComboBox and another RadAjaxPanel occupying a tab in a RadTabStrip.  The first tab is always shown.  The second is for displaying an ASCX that may or may not be shown.

When I select certain values of the combobox, its SelectedIndexChanged event loads and sets up an ASCX on the second tab.  Everything is working properly except that when I hit the submit button on the FormTemplate itself, the ASCX Required Field Validators never fire.  (Even though I've accessed and enabled them directly in the SelectedIndexChanged event.  I know they're there.)

I have my RadAjaxManager set up as follows:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadComboBox1">
                <UpdatedControls >
                    <telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1" />
                    <telerik:AjaxUpdatedControl ControlID="RadTabStrip1" />                  
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

Also it appears so far that although the control is loaded I cannot access it as usual in the RadGrid's InsertCommand e.item FindControl.

Suggestions?

Hi Boris,

Could you please provide us with your code declaration and the related code behind in order to investigate the issue further? I would suggest you to check out the following help topic which describes how to ajaxify controls wrapped in RadAjaxPanel and added to RadAjaxManager settings .

All the best,

Let me get back to you.  I need to give this some more thought.  I may have to submit a formal ticket for this one.  

(And as usual the current code is probably too complex and proprietary to hand out.  I'll try to come up with a demo.)

My apologies to one and all.

After Re-reading The Fine Manual I believe my main mistake was having RadAjaxPanels in there in the first place. 

It looks like everything is behaving normally now with only a RadAjaxManager.

Thanks.
