The RadGallery item has a property SelectionMode, inherited from ItemsControlSelector.
But it is not implemented.
I would like to use the Gallery to select multiple options instead of only one:
*the gallery shall keep open on select one item
*the items shall toggle selection on item click

In MVVM scenario, DropDownContent of the RibbonDropDownButton is databound.

In the DropDownContentTemplate, there is a RadContextMenu with menu items with Commands. These Commands do not fire. This has worked till Q2 2014.

When desktop is shared through Office Communicator 2007 RibbonWindow is not repainting properly. The same issue can be reproduced through a remote desktop connection - when the RibbonWindow is running in a Aero Windows theme, the RibbonWindow chrome is painted in black when accessed through a remote desktop.

Add a possibility to imitate fullscreen mode.

Drawing graphics inside the RadRibbonWindow causes performance hit. More information and videos in the support thread

Allow extending the Window glass frame into the RadRibbonWindow content

ApplicationName is  off center when TabStripAdditionalContent contains an element with long text/content

Initially RibbonView gets rendered design-time. Trying to edit RibbonTab-s or add new one causes the whole control to dissapear in the designer. Clean and rebuild of the solution doesn't help -- cleaning the Shadow cache of Visual Studio Designer is the onliest thing that helps.

The issue reproduces with Class Library containing the Ribbon setup and IsWindowsThemeEnabled property of RibbonWIndow turned off (default value).

Implement AutoHide functionality in the RadRibbonWindow like the Office 2013 has. 

A black border is displayed around the window when SizeToContent is set on Windows7  with disabled aero.

When the RibbonWindow contains WindowFormsHost element with WinForms controls and the window is resized (for example with the Maximize/Restore Down buttons), the resizing is slow.

Note: The issue is reproducible only if the  RadRibbonWindow.IsWindowsThemeEnabled static property is set to False

When the RadRibbonView is hosted in RadRibbonWindow under Windows7, the top part of the default inner border of the RadRibbonWindow is cut.

RadRibbonSplitButton text is too close to the border of the button due to lacking padding in the TextBlock holding text. Also the Text is a few pixels off vertically compared to the other ribbon buttons.

RibbonWindow Title is displayer on multiple lines when its value is set to a very long string and used on Windows7(Aero).

The minimized content is not closed when you click outside of the ribbon when you have explicitly MouseUp-ed outside of the RibbonView aria.

 Improve the performance of the keytips functionality.

As a workaround set a Margin="0,0,1,0" to the RadBibbonView in order to have the functionality working in the area of the RadRibbonView.

RibbonView galleries should support keyboard navigation, for example, up/down buttons should move the focus to the gallery, and move selection accordingly.
