Hi,
I am using Telerik with ASP.NET.
There is some process which takes much time to complete. At the time of process RadAjaxLoadingPanel viwed successfully in my development environment.
But when I run the application from IIS then after some tile ajax loading panel disappear. At the time back end process till in progress and finally no message about the completion success or failure status.
Some code:
Master page:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" AsyncPostBackTimeout="1200">

<Scripts>

<telerik:RadScriptReference Path="JS/jquery-1.11.1.min.js

</Scripts>

</telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" UpdatePanelsRenderMode="Inline><

telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanelProcess" Enabled="true" runat="server" IsSticky="true" MinDisplayTime="300" Style="position: absolute; top: 0; left: 0; height: 100%; width: 100%">

Processing..

</telerik:RadAjaxLoadingPanel>

Content page:

<telerik:RadWindowManager ID="RadWindowManagerProcess" runat="server"</telerik:RadWindowManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanelProcess1" Enabled="true" runat="server" IsSticky="true" Style="position: absolute; top: 0; left: 0; height: 100%; width: 100%;" RegisterWithScriptManager="true"> Processing...</telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest" LoadingPanelID="RadAjaxLoadingPanelProcess1">

</telerik:RadAjaxPanel

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function confirmCallBackFn(arg) {

var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>")

if (arg) {

$find("<%= RadAjaxPanel1.ClientID%>").ajaxRequestWithTarget("<%= RadAjaxPanel1.UniqueID %>", "PanGenerate");

}

else {

ajaxManager.ajaxRequest('Cancel');

}

</script>

</telerik:RadCodeBlock>

CS:

protected void btnCrud_ProcessClick(object sender, EventArgs e){

//.........

if (totalCard >

{ var msg = new StringBuilder();

msg.Append("Total " + totalCard + " records found.");

msg.Append("/br");

msg.Append(" Do you want to process " + CalculativeCard + " records ?");<br> RadWindowManagerProcess.RadConfirm(msg.ToString(), "confirmCallBackFn", 370,170, null, "Confirmation Message")

}

So what can I do???
Please inform me if any more information required..
Thanks in advance
