RadManger in initial page load

[Waleed Seada]

Hello all,

How can I show a loading panel while the page is loading, I have found an example in the help, but doesn't work for me.

I have a masterpage with RadSplitter on it and I did the following:

RadManager settings in .aspx:

<telerik:RadAjaxManager ID="RadMgr" runat="server" OnAjaxRequest="RadMgr_AjaxRequest">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadMgr">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="Panelcontrolholder" LoadingPanelID="LoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

JS:

script type="text/javascript">
// Show Loading Panel in the first application initialization phase
window.onload = function()
{
    setTimeout( function()
    {
        window[ "<%= RadMgr.ClientID %>"].AjaxRequest("InitialPageLoad");
    }, 200);
}

CS:

protected void RadMgr_AjaxRequest(object sender,AjaxRequestEventArgs e)
    {
        if (e.Argument == "InitialPageLoad")
        {
            //simulate longer page load
            //System.Threading.Thread.Sleep(2000);
            MainPanel.Visible = true;
        }
    }

What is missing here !!

Best regards,
Waleed

Hello Guys,

I change this JS as following:

<telerik:RadCodeBlock ID="cb1" runat="server">
    <script type="text/javascript">
        // Show Loading Panel in the first application initialization phase
        window.onload = function()
        {
            setTimeout( function()
            {
                $find("<%=RadMgr.ClientID%>").ajaxRequest("InitialPageLoad");
                //window[ "<%= RadMgr.ClientID %>"].AjaxRequest("InitialPageLoad");
            }, 200);
        }
    </script>
</telerik:RadCodeBlock>

It works, but when the page is already there, I wanted to start as soon as the page start loading ....

Any suggestions
