A user control contains a tabcontainer. When aspx page loads, the user control is not visible. Ajax toolkit script function tries to set focus on tabcontainer and it throws exception : "Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."
The problem occurs in IE 8 with 11/16/2011 release. It worked OK with sept. release.
Comments: zahidkamran, download the source code to find the file... modify and recompile the project. the new AjaxControlToolkit.dll is in the server\ajaxcontroltoolkit\bin\debug folder. HTH
