Visual Studio 2010 Beta 2 and ASP.NET AJAX

by Rok Bermež 15. December 2009 11:16

If you are trying to use ASP.NET AJAX functionality in combination with Master pages you will get a JS Error 'get_postBackElement().id' is null or not an object.'.

Current workaround is quite simple. Just set ClientIDMode property of the Page to AutoID. (ClientIDMode="AutoID").
