1. No problems with 2012.2.912 (most recent before 2013 Q1).
2. Upgrade to 2013 Q1.
3. On ItemDataBound and on ItemCommands, I'm unable to read "text" problem for grid columns via the following code.  In every case, even when data exists in the column, item("ColumnName").Text returns " ".

ScriptManager.RegisterStartupScript(Page, Me.GetType, "Goon", "window.scrollTo(0,0);", True)

but is only a refresh of Pgina and the scrollbar is always positioned at the bottom so the page does not return at the beginning of the list.

Hi,
I have aspx page it has usercontrol, radwindow,  and inside radwindow it has radrotator.

User control  has gridview when user click linkbutton inside gridview, I am showing radwindow as a popup.
When loading aspx page I am binding data to radrotator.

When user clicks link current item is not setting properly. 
But when the window is closed and reopened it works fine.

Am I missing something?
How to force it to load correct index?
In first popup it does goes through
 radRotator.set_currentItemIndex(RadImgItems[name].get_index(), false);
