In __ExtenderControlBase.cs : 281__
__RegisterLocalization()__ is called also if AjaxControl Toolkit isn't used on the current page.
This will result in an Javascript error:
"Uncaught TypeError: Cannot read property 'UI' of undefined"
Comments: Would you please provide a sample project so that we can reproduce the issue? ExtenderControlBase.OnPreRender method is called only if a page has any of the AJAX Control Toolkit extenders
