Updating text on page at regular intervals

Okay, I am pretty new to the Atlas/AJAX system, so im just now learning some of these tricks and whatnot. I have a page that basically needs to load a quote every 30 seconds or something. Right now, I have the page setup so that the text can be changed by clicking a javascript button without refreshing the page, but I am trying to get that function to call based on the Timer control included with atlas. any ideas for refreshing text at a regular time interval would be greatly appreciatedthe timer control would be what you want, but there's no way to tell what could be wrong without you showing some code you are trying

Hi,

this is an ideal scenario for theUpdatePanel control. The page can be refreshed at regular intervals by aTimer control. Check the following example: 

<%@. Page Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> protected void TheTimer_Tick(object sender, EventArgs e) { lblUpdate.Text = DateTime.Now.ToString(); }</script><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <asp:ScriptManager ID="TheScriptManager" runat="server"></asp:ScriptManager><%-- Timer --%> <asp:Timer ID="TheTimer" runat="server" Interval="2000" OnTick="TheTimer_Tick"></asp:Timer><%-- UpdatePanel --%> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="TheTimer" EventName="Tick" /> </Triggers> <ContentTemplate> <asp:Label ID="lblUpdate" runat="server"></asp:Label> </ContentTemplate> </asp:UpdatePanel> </form></body></html>
