RadTreeView for ASP.NET AJAX

The problem

You receive an error message like "Stop running the script" or "A script is causing IE to run slowly" when you expand a node which loads its child nodes on demand. A timeout error could occur as well.

The resolution

You can use one of the solutions below:

1. Disable debugging in your web.config file:

Note that this is the recommended setting for a production environment.

CopyXML

<compilation debug="false">

Or, use the second approach described below.

2. Set the ScriptMode property of the ScriptManager / RadScriiptManager to "Release":

CopyASPX

<asp:ScriptManager ID="ScriptManager1"     
                   runat="server"     
                   ScriptMode="release">
</asp:ScriptManager>

CopyASPX

   <telerik:RadScriptManager ID="RadScriptManager1"     
                             ScriptMode="Release"    
                             runat="server">
   </telerik:RadScriptManager>
