Reproduces with Q2 2015 binaries.


Available in R2 2017 SP

You can't add a RibbonTab from design-time. It seems that manipulating RibbonView using the additional option in design time isn't working.


Available in LIB version: 2017.2.605

Pressing Alt to activate the KeyTips and then Alt+Tab leads to NullReferenceException (especially on slower machine )


Available in LIB version: 2017.2.605

In scenarios with more than one monitor when the RibbonWindow is run on 64bit process and e.g. using VBE7.dll, the WM_NCHITTEST message, which is sent to the window in order to determine what part of the window corresponds to a particular screen coordinate, could provide lParam with value which overflows Int32.


Available in LIB version: 2017.1.313

Possible workaround is to set the ApplicationButtonVisibility property to Hidden.

This is reproducible only if the ribbon window chrome is enabled (IsWindowsThemeEnabled=False).


You can resolve this by registering an input binding for the Alt+Space key gesture and attaching it to the Telerik.Windows.Controls.RibbonView.Shell.SystemCommands.ShowSystemMenuCommand RoutedUICommand.

static MainWindow()
{
     var keyBinding = new KeyBinding(Telerik.Windows.Controls.RibbonView.Shell.SystemCommands.ShowSystemMenuCommand, new KeyGesture(Key.Space, ModifierKeys.Alt));
     CommandManager.RegisterClassInputBinding(typeof(RadRibbonWindow), keyBinding);
     RadRibbonWindow.IsWindowsThemeEnabled = false;
}

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

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).

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.
