Solution

There are 2 ways to fix this issue:

  1. To fix this, set the "EnableScriptCombine" attribute to "false" on the RadScriptManager control.

  2. Instead of using the RadScriptManager, you can use the ASP.NET toolkit script manager in its place, using the same ID attribute as shown below:

<ajaxToolkit:ToolkitScriptManager runat="server" ID="ScriptManager1" ScriptMode="Release" />
