Enabling ModalPopupExtender from ServerSide Code in the Ajax Control Kit
Getting the ModalPopupExtender to work from Server Side Code is quite simple once you know how. The control can be triggered via code with the Show method, but you need a dummy client control for the TargetControlID in the ModalPopupExtender.
I've used an ASP.NET HiddenField which will render correctly without using style sheet magic to hide it from the form.
The complete code is shown below:
<!-- Hidden Field -->
<asp:HiddenField ID="hidForModel" runat="server" />
PopupControlID="pnlIssues" >
<!-- Panel -->
<asp:Panel ID="pnlIssues" runat="server"  
BorderColor="Black" BorderStyle="Outset"  
BorderWidth="2" BackColor="Wheat" Width="400px"  Height="106px">
       <h2 class="style2">
         <h3> <asp:Label ID="lblWarning" 
runat="server"> </asp:Label></h3>
 <!-- Label in the Panel to turn off the popup -->
 <asp:ImageButton ID="btnWarning" runat="server"
                ImageUrl="~/images/buttons/update.png" />

C# Code
lblWarning.Text = "This is a popup warning";
Enjoy and remember to vote.
