0x800a138f - JavaScript runtime error: Unable to get property 'UI' of undefined or null reference

You might be wondering what is this error and what you have to do to resolve “0x800a138f - JavaScript runtime error: Unable to get property 'UI' of undefined or null reference” error. Here is the answer for you.

Reason for this error: This error normally occurs when you use ScriptManager, like below, because most of the controls from AjaxControlToolKit work using Ajax script unfortunately many Ajax scripts are not updated in ScriptManager.

<asp:ScriptManager ID="ScriptManager1" runat="server">


Solution to resolve this error: You have to use ToolkitScriptManager instead of ScriptManager. ToolkitScriptManager adds most of the updated Ajax Script. Your code after changing must be like below,

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">

After changing to ToolkitScriptManager run your project and see the output.
