Updateprogessbar is not working when Setting AssociatedUpdatePanelID?
I have two updatepanel and a progressbar on the page. If I set the AssociatedUpdatePanelID, then progressbar is not working, without setting AssociatedUpdatePanelID progress bar is working but the problem is working for both updatepanel. But I need to work on one updatepanel. <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Click" /> <asp:Button ID="Button2" runat="server" Text="Button2" OnClick="Button2_Click" /> <asp:UpdateProgress runat="server" ID="prg" AssociatedUpdatePanelID="upnl"> <ProgressTemplate> <img src="Images/progressbar.gif" /> </ProgressTemplate> </asp
