Microsoft JScript runtime error: 'AjaxControlToolkit' is undefined |

MultiHandleSliderExtender

Problem

I have an AJAX MultiHandleSliderExtender Control and ToolkitScriptManager on the web page and everything work fine. Then I decided to include a Master Page to it, at runtime, I received the following errors

Message: Invalid character
Line: 1
Char: 3
Code: 0

Message: 'AjaxControlToolkit' is undefined
Line: 182
Char: 5
Code: 0

This is a very weird error, the page work fine without the present of a Master Page. I started to look around and found the solution here. The solution is to set the "CombineScripts" property of the ToolkitScriptManager to false.

<ajaxToolkit:ToolkitScriptManager runat="server" ID="ajaxScriptManager" EnablePartialRendering="true" CombineScripts="false" />

I have an AJAX MultiHandleSliderExtender Control on the web page and everything work fine. Then I decided to include a Master Page to it, at runtime, I received the client-side error "Microsoft JScript runtime error 'null' is null or not an object".
This is a very weird error, the page work fine without the present of a Master Page. I started to look around and found out that the value of the ID and BehaviorID have to be identical. If you happen to come across the same error, give this solution a try. It work for me.
