How Do I: Use the ASP.NET AJAX Timer Control?

The AJAX Timer control enables a portion of an ASP.NET web page to be dynamically updated at a regular interval, rather than needing the user to perform an action such as clicking on a button.

You can also use the time to redirect after a submission. If a user joins your site they are usually directed to a confirmation page. On the confirmation page you can set the timer to redirect the user back to your home page or to the login page.

Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs)

Response.Redirect("~/Default.aspx")

End Sub

</script>

<body>

<h1>Submission successful!</h1>

<p>Thank you for your submission</p>

<p>If you are not redirected in 5 seconds, click <asp:HyperLink runat="server" ID="lnkredirect" NavigateUrl="~/Default.aspx" Text="here"></asp:HyperLink>

</p>

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<asp:Timer ID="Timer1" runat="server" EnableViewState="false" Interval="5000" OnTick="Timer1_Tick">

</asp:Timer>

</form>

</body>

</html>
