If you have a RadComboBox inside a ControlPanelItem, when you open the RadComboBox's dropdown and select an item, the ControlPanelItem is not closed. As a workaround, you can manually capture the mouse. Please check the attached project.

To reproduce the problem, there need to be defined a huge amount of columns(400-500). The workaround is to call the Clear method of the Columns collection of RadGridView

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.

A TargetName = "FilterIcon" should be added to the foreground setter in the trigger in the control template of the FilteringDropDown.

As of R1 2018 the GetCellContent method is no longer used for exporting a custom column content. Instead, the GetExportCellContent one of GridViewBoundColumnBase needs to be overriden.

Currently, RadGridView's data engine relies on TypeDescriptor.GetProperties, when resolving the set of properties accessible through a certain type. Apparently, this API hides the properteis from the interface, as they are not accessible throught the concrete type.
