GridViewHeaderCell are not draggable when RadGridView is hosted in DropDownButton.DropDownContent. Trying to drag a cell does not trigger drag events.

The problem should be resolved with lib version 2015.3.1012.

GroupFooterRowStyleSelector is not persisted, when you expand and collapse a group

PropertyChanged event is called for a cell with nullable value when is in edit mode and click on another cell

GridViewColumnGroups.Header does not respect any content different from string when EnableColumnGroupsVirtualization is True.

*** Workaround: Use HeaderTemplate property instead or set EnableColumnGroupsVirtualization to False in all themes different than Windows8, Windows8Touch and ExpressionDark.

The problem should be resolved with version Q2 2015 SP1.

GridViewColumnGroup.HeaderTemplate is not respected in Windows8, Windows8Touch and ExpressionDark themes. Instead, the name of the column group is its content.

This is reproducible with both StyleManager and Implicit Styles.

Should be resolved with lib version 2015.2.720.

The problem can be reproduced only when the previously focused element is in ToolBar or RadToolBar. It is not reproducible in the default scenario. 

Should be resolved with lib version 2015.2.713.

А new virtualization mechanism for ColumnGroups will be introduced with Q2 2015. A property EnableColumnGroupsVirtualization is exposed with default value True for enabled virtualization. Setting it to False will enable the old logic.

The fix will be available with Q2 2015.

Just run the attached project and scroll horizontally to the very end several times (at least two times).
I tried disabling the column virtualization but this did not help.

This issue will be resolved with Q2 2015.

Focus stops moving but selection keeps moving when navigating through the keyboard down key. When the window is stretched so that the ScrollBar is not visible, the issue could not be reproduced.
