Issue with user control getting loaded with asp:timer

I have been working on a web application which requires loading a user control using asp:timer control. Application is completely based on widgets.

The default page has number of widgets that are loaded dynamically at runtime and all widgets has the facility to enable or disable timer.

All events were working fine except "User Widget" not firing any events. Here is how the code is :-

WidgetTimer.ascx















UserControl.ascx


<%@ Control Language="C#" AutoEventWireup="true" CodeFile="DataListMgrReal.ascx.cs" Inherits="DataListMgrReal"%>










Select Repository






PageSize="25"
AutoGenerateColumns="false"
GridLines="None"
CssClass="gridViewData"
Height="159px">











I have been struggling to find the issue. Then i have tried creating a new web app and have tried with just the above snippet and that works fine.

After some modifications the btnUpdate_Click stated working but only works for the second click.

i have come accross the following articles...

Application was so complicated so the only detail that has skipped out of my mind is "UserControl" ID property.

I am not assigning ID property manually which has been causing the issue all the time. I have finally fixed the issue now its a relief......

Hope this might be helpful for someone like me with this odd combination.

Never overlook a minute detail !!!
