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: Just download the June 2012 AjaxToolKitd.dll to see if it would solve the IE8 error, and it doesn not. I had to download the source code and found that the fix mentioned is not in there. I had to add "desterly fix" from Nov 30 2011 at 4:04 PM fix to get it to work. Also learned the fix mentioned is in the extended.dll so you have to compile the client folder, then the server folder, and the test website folder to get the AjaxToolKitd.dll from the website bin that is needed. This bug shoudn't be closed as it is not resolved in the June 2012 build. Thanks, Keith
