I have an asp.net timer control on a page that needs to fire a javascript event on Tick event.  I can normally fire a javascript call using ClientScript.RegisterStartupScript, etc. and I have event tried to fire one on the ScriptManager.RegisterStartupScript within the Tick event.  I get the infamous "Sys.WebForms.PageRequestManagerParserErrorException" exception. 

 Has anyone got an example of calling a RegisterStartupScript(or calling/running a javascript function from the server methods) on the Tick event of the timer control?

Joseph,

Here is the working barebones implementation:

<form id="form1" runat="server">

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

</asp:ScriptManager>

<div>

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<asp:Timer ID="Timer1" runat="server" Interval="30000" OnTick="Timer_Tick">

</ContentTemplate>

</asp:UpdatePanel>

</div>

</form>

Thanks, worked like a dream.  Say hi to Rockford Lhotka. 

Joseph,

Next time I see him, I will.  He says he might come to Atlanta for DragonCon, but we'll see.  Everyone calls him Rocky, by the way.  I don't think I quite have the nerve to try "Rockford" on him.  ;)
