Hello!
i have attached my code below.


 <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
        <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
        <UpdatedControls>
       <telerik:AjaxUpdatedControl ControlID="panel1" />
      <telerik:AjaxUpdatedControl ControlID="samplediv" />
        </UpdatedControls>
        </telerik:AjaxSetting>
        </AjaxSettings>
       <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="Timer1" >
        <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="samplediv" />
        <telerik:AjaxUpdatedControl ControlID="ajaxbtn" />
        </UpdatedControls>
        </telerik:AjaxSetting>
        </AjaxSettings>
        </telerik:RadAjaxManager>
        <br />
         <asp:Panel ID="panel1" runat="server">
        <asp:Timer ID="Timer1" runat="server" Interval="2000" ontick="Timer1_Tick" Enabled="false">
        </asp:Timer></asp:Panel>
        <div id="samplediv" runat="server" style="border:solid 1px grey;height:180px;width:250px;overflow:scroll;" />  
<telerik:RadCodeBlock ID="radblk" runat="server">
 <script type="text/javascript">
function chattext()
{
    var ajaxmagr = $find("<%=RadAjaxManager1.ClientID%>");
    alert(ajaxmagr);
    ajaxmagr.ajaxRequest("chat");
}

</script>       
        </telerik:RadCodeBlock>


cs code..


protected void Timer1_Tick(object sender, EventArgs e)
    {
        string s = "chattext();";
        RadScriptManager.RegisterStartupScript(this, this.GetType(), "s", s, true);
    }
    protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
    {
        if (e.Argument == "chat")
        {
            
            samplediv.InnerHtml += " sample text <br/>";
           
        }
    }






i want to call a js funtion in timer tick.  but i got ajaxmgr as null in js alert.
whats wrong in my code? 

thanks.

Hello,

It seems that the Startup script is registered too early on the page and the RadAjaxManager is still not initialized. please try to set time out like this:
 
Let me know if this helps.

Kind regards,

This is great, it worked for me.
