LoadingPanel and IE10 problem

[Cheri Verdend]

In IE10 when I include a LoadingPanel in either RadAjaxPanel or RadAjaxManager, a button click that should produce an AJAX callback, does nothing. If I switch to compatibility view, then the button click works properly. (I saw the sticky, but it seems to be directed at older browsers.)

Below is a simplified page that demonstrated the problem using both a LoadingPanel and RadAjaxPanel .

<asp:ScriptManager ID="ScriptManager1" runat="server" EnableTheming="True"></asp:ScriptManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"></telerik:RadAjaxLoadingPanel>

   
<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" style="margin:40px;" LoadingPanelID="RadAjaxLoadingPanel1" >

    RadAjaxPanel test:

    <asp:Button id="Button1" runat="server" text="Test 1" onclick="Button1_click" />

    <br /> <br /> <asp:Label ID="timestamp1" runat="server"></asp:Label>

</telerik:RadAjaxPanel>

　

   
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" RestoreOriginalRenderDelegate="false">

   <AjaxSettings>

     <telerik:AjaxSetting AjaxControlID="Button2">

       <UpdatedControls>

         <telerik:AjaxUpdatedControl ControlID="AjaxPanel" LoadingPanelID="RadAjaxLoadingPanel1" />

       </UpdatedControls>

     </telerik:AjaxSetting>

   </AjaxSettings>

</telerik:RadAjaxManager>

<asp:panel ID="AjaxPanel" runat="server" style="margin:40px;">

     RadAjaxManager test:

     <asp:Button id="Button2" runat="server" text="Test 2" onclick="Button2_click" />

     <br /><br />

     <asp:Label ID="timestamp2" runat="server"></asp:Label>

</asp:panel>

 

And here's the codebehind for the buttons:

Sub Button1_click(ByVal sender As Object, ByVal e As System.EventArgs)

   timestamp1.Text += "<br>" & Now

End Sub

Sub Button2_click(ByVal sender As Object, ByVal e As System.EventArgs)

   timestamp2.Text += "<br>" & Now

End Sub

This page works in Chrome, FF, older versions of IE, and IE10 compatibility view, but not in plain IE10. As soon as I remove the LoadingPanel, then it also works in plain IE10.

I assume I've overlooked something simple. But I can't find it. Any help would be appreciated!

Hello Cheri,

Based on your description and the markup you have provided I tried to reproduce the issue on my side, but without success.

Therefore attached you will find a small sample project that can be uses for reproducing the problem. Here is a video that I have recorded against the testing project. You can also try to additionally modify the attached project if it is needed for reproducing the problem.

In case you succeed send us the exact steps that must be followed in order to replicate the issue at my end.

Thank you for your reply, Deyan. 

I was able to use your sample project and a trial download of the latest release to determine the problem is connected with the version of Telerik AJAX controls I'm using. 

Here is a screencast that shows the problem: http://www.screencast.com/t/JMYyzToT57L 

As you can see in the video, when I run your sample project page using dlls from the 2011.3.1305.40 release, the page works in IE10 only when it's in compatibility view. But when I switch to using dlls from the 2013.2.717.40 release, the page works in both IE10 regular and compatibility view.

Is there a workaround or hotfix that will correct this problem in the version I'm currently using - 2011.3.1305.40 ?

Hi,

As you have confirmed this has been fixed in our latest release. Our hotfix build is based on the currently official release, but not to a previous versions of RadControls. Therefore, we would recommend you to upgrade to our latest official release.
