Hi

"Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object".

And interrups the running of the program..
ASPX code is:

 

 

 

 <telerik:RadAjaxManager ID="radAjaxManager" runat="server" ClientEvents-OnRequestStart="requestStart" 
                OnAjaxSettingCreating="radAjaxManager_AjaxSettingCreating">  
                <AjaxSettings> 
                    <telerik:AjaxSetting AjaxControlID="RadGrid1">  
                        <UpdatedControls> 
                            <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="ajaxLoadingPanel" /> 
                        </UpdatedControls> 
                    </telerik:AjaxSetting> 
                </AjaxSettings> 
                <ClientEvents OnRequestStart="requestStart" /> 
            </telerik:RadAjaxManager> 
            <telerik:RadAjaxLoadingPanel ID="ajaxLoadingPanel" runat="server" Height="75px" 
                Width="75px" HorizontalAlign="Left" BackgroundPosition="BottomLeft" Direction="LeftToRight">  
                <div style="position: absolute; left: 500px; top: 200px">  
                    <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'

Hi,

I have checked your design and have found no issues with it.Could you post the OnRequestStart js function that you have created . It might be causing the issue 

Thanks,
Princy

Hi Princy,
                Here it is my onRequestStart event for your reference,

function requestStart(sender, args) {  
 
if (args.get_eventTarget().indexOf("btnExport") > 0)  
args.set_enableAjax(false);  
}  
 

-Thanks

Hi,
          Now i am getting another problem for implementing LoadingPanel. Early i removed  EnablePartialRendering="false"  from the ScriptManager section so that some of the forms LoadingPanel working fine without any error.

I intrduced the same scenario for my another new form. But now i am getting the following error 
"htmlfile: Unknown runtime error".

 So  what to do for some of my webforms loadingpanel working fine by removing  EnablePartialRendering="false",  but applying the same scenario some other form is getting the htmlfile: Unknown runtime error".

I am totally confusing about the above error, so what to do to implementing the LoadingPanel to my form. So give me suggession to do it.

-Thanks
