Hi Monaj,

The timer references Timer1 but when the user control gets rendered it will have a newly assigned name because it is on a user control. Do a View Source and you will see this is the case

<asp:AsyncPostBackTrigger ControlID="timer1" EventName="Tick"  />

Add ClientIDMode="Static" as shown below. This assumes this control is only dropped on the page one time, otherwise you should set ControlID of timer1 postback triggers to Timer1.ClientID()


<asp:Timer ID="timer1"
ClientIDMode="Static" runat="server"
Interval="1000" OnTick="timer1_tick"></asp:Timer>
