I have a page in my asp.net web forms with a timer and an update panel. My page is on a Master page.

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<br />
<asp:Timer ID="Timer1" runat="server"
Interval="12000" OnTick="Timer1_Tick">
asp:Timer>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<fieldset class="container">
<legend><strong>Formal Teacher Evaluationstrong>legend>
<div class="row">
<div class="col-lg-2">
<asp:Label ID="label1" runat="server">asp:Label>
div>
div>
fieldset>
ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
Triggers>
asp:UpdatePanel>
asp:Content>

in code behind I have this:

protected void Timer1_Tick(object sender, EventArgs e)
{
label1.Text = "Time updated : " + time;
}

It updates after the interval time lapsed. But, the panel only updates once. How can I make the update panel updates every after interval time?

Thank you for any help.

I have updated your code. It is working for me.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="WebApplication1.Test" %>
Untitled 1

Interval="12000" OnTick="Timer1_Tick">

Formal Teacher Evaluation

Thanks Srikant for the prompt reply. I moved the timer inside the update panel but the result is the same. It didn't update after the first update.

erratum

It works now. Now, instead of a label, I used now my InsertUpdate function. Sad to say, the update panel didn't update after the first update.
protected void Timer1_Tick(object sender, EventArgs e)
        {
            InsertEvaluation();
        }
any suggestions?
