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.

Will be available with LIB version 2015.3.1026.

As a workaround, one can look this up by accessing the Object/DbContext directly.

Workaround is to specify that the format string should contain only the required member path:

<telerik:GridViewDynamicHyperlinkColumn Header="ID" DataMemberBinding="{Binding ID}" NavigateUrlMemberPaths="WebUrl" NavigateUrlFormatString="{} {0}"  TargetName="_blank"/>

A kind of a workaround for the user: resize any column/the entire window or collapse the row details.

The designer crashes with this exception:
InvalidOperationException: 'GridViewColumnGroupRow' TargetType does not match type of element 'GridViewColumnGroupRow'.

See the attached screenshot. It's from a new project, after clean and rebuild.

Visual studio: 2015
Telerik UI for wpf: 2015.2
Implicit styles, Windows8 theme.

* The problem is not theme specific. As a workaround, use no xaml binaries instead of xaml files.

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.

I would like to be bale to modify at once several cells of a GridViewComboBoxColumn, when using the common ItemsSourceBinding for all rows (in my GridView, the selection ​is: SelectionMode="Multiple" SelectionUnit="FullRow").
So I would like for the selected rows to apply the same value as the edited cell.
