ASP.NET AJAX Modal Popup Extender Responding to Server Code on Timer

I have a modal popup extender tied to a asp:panel control that I want to show when the timer on an asp:updatepanel reloads executes the tick method. The tick method calls another method that checks for specific conditions and if all the conditions are met, I call:

ClientScript.RegisterClientScriptBlock(this.GetType(), "key", "$find('modalPopupExtender').show();", true);

I have the TargetControlID on the extender control set to the asp:updatepanel. So far this is not popping up the modal window.

Should I have the TargetControlID set to the timer control inside of the asp:updatepanel???

What am I missing?

Solution

  • I've tried the above answers and suggestions. I found that putting a dummy div tag on the page with the "runat" set to server and setting the extender control's TargetControlID to the dummy div helped.

    I also commented out the ClientScript code and added modalPopupExtender.Show(). This allowed the modal window to be displayed.
