The feature should be similar to the TabStripAdditionalContent(https://docs.telerik.com/devtools/wpf/controls/radribbonview/how-to/howto-additional-content-near-help-icon)  of RadRibbonView and RadTabControl. It would be useful to include additional information and functionality like in the MS Office tools. For example the Outlook app (check the attached image).

As a workaround, you can set the FocusVisualStyle of the DropDownPopupContent element in the template of the RadRibbonDropDownButton  to null or add an implicit style for ContentControl setting the FocusVisualStyle to null.

When we have specified RibbonGallery, and we resize the RibbonView fast enough, the RibbonGallery is collapsed even if there is enough space to visualize.

When the ContentHeight is set in Xaml or before the control is loaded it is not respected. 

The issue is reproducible in Fluent theme as well.

The current workaround is to handle the RadTabItems' PreviewMouseLeftButtonDown event like so:

         public MainWindow()
        {
            InitializeComponent();
            EventManager.RegisterClassHandler(typeof(RadRibbonTab), PreviewMouseLeftButtonDownEvent, new MouseButtonEventHandler(OnClick), true);
        }

        private void OnClick(object sender, MouseButtonEventArgs e)
        {
            var tab = sender as RadRibbonTab;
            var ribbon = tab.ParentOfType<RadRibbonView>();
            if (ribbon.IsApplicationMenuOpen)
            {
                ribbon.SelectedItem = tab;
            }
        }

 

In the Crystal theme, the TitleBarBackground property is set through a style trigger to a static value. This leads to an unexpected result in the dark variation of the theme. 

As a workaround you can use the following style:

  <Style TargetType="telerik:RadRibbonView" BasedOn="{StaticResource RadRibbonViewStyle}">
            <Style.Triggers>
                <Trigger Property="IsHostedInRibbonWindow" Value="True">
                    <Setter Property="TitleBarBackground" Value="{telerik:CrystalResource ResourceKey=AlternativeBrush}"/>
                </Trigger>
            </Style.Triggers>
   </Style>

 

 

The attached project demonstrates a possible approach for handling this - by editing RadRibbonWindow's control template and specifying a converter for the PART_Icon Image's Width and Height bindings. The converter in turn takes into account the DPI of the current monitor.

Black border appears around the window when SizeToContent is set to WidthAndHeight

To reproduce this:

• Set the RadRibbonButton LargeImage/SmallImage to a property that is larger than 16 (small image) or 32 (large image).
• Set IsAutoSize to False. This will stretch the image on all available space for the button.
• Set IsAutoSize to True. This should uniform stretch the picture so that it fills the auto size of 16 or 32 pixels. However, the image doesn't stretch, instead its Stretch is set to None, which expand the image to its original size. This leads to the clipping.

To work this around, avoid setting the IsAutoSize property. Or use smaller pictures - 16 or 32 pixels.

In the application menu, we have placed a RadRibbonSplitButton. When the application menu is open, and we press Tab and Space key, the application menu is closed and the UI unresponsive until the mouse leaves the control.

A binding error occur in the output on Windows7 without aero.
(System.Windows.Data Information: 10 : Cannot retrieve value using the binding and no valid fallback value exists; using default instead. BindingExpression:Path=IsActive; DataItem=null; target element is 'Button' (Name='PART_MinimizeWindowButton'); target property is 'NoTarget' (type 'Object'))

If a contextual tab is collapsed when the contextual group is activated and then its visibility is set to Visible, the tab is not shown (only if you reopen the group).

Available in LIB version: 2015.2.803

When the Taskbar is auto-hidden, if the RibbonWindow is maximized, the taskbar cannot be displayed.

Available in LIB version: 2015.1.2303

When the Visibility of the RadTabItem is set to Collapsed the keyboard navigation does not work as expected. 

WindowChrome is not updated after dynamic theme change on Windows7(from Aero to NonAero)

Will be available in Q1 2015 SP.

Every KeyTipControl is placed inside a Popup. Expose properties which could control the Popup position.
