If you open the dropdown of the RadRibbonComboBox using the keytips support and then navigate to an item, and select it using the arrow keys, the selection is wrong. It selects the next item instead of the one highlighted by the keyboard navigation.

Release LIB 2020.2.6.08

Setting the KeyTipService.AltAccessText attached property on a RadRibbonGroup element should display a keytip on the dialog launcher of the group, when the keytips are activated.

Currently, if the group is collapsed, you can expand it using its AccessText. However, in this case the keytip of the dialog launcher is not displayed.

To work this around, subscribe to the Loaded event of RadRibbonGroup and set the KeyyTipService.AccessText property directly to the RadRibbonButton representing the dialog launcher.

private void RadRibbonGroup_Loaded(object sender, RoutedEventArgs e)
	var group = (RadRibbonGroup)sender;
	var button = group.ChildrenOfType<RadRibbonButton>().FirstOrDefault(x => x.Name == "DialogLauncher");
	if (button != null)
		KeyTipService.SetAccessText(button, "D");

In the Loaded event of the RibbonWindow, use the Telerik.Windows.Controls.RibbonView.Shell.WindowChrome class to get the current window and set its ResizeBorderThickness property to 0. 

public MainWindow()
    this.Loaded += MainWindow_Loaded;
void MainWindow_Loaded(object sender, RoutedEventArgs e)
    Telerik.Windows.Controls.RibbonView.Shell.WindowChrome chome = Telerik.Windows.Controls.RibbonView.Shell.WindowChrome.GetWindowChrome(this);
    chome.ResizeBorderThickness = new Thickness(0);

1. When the RibbonWindow is maximized the draggable area ends below the WindowTitle

2. In Normal state - the draggable area could be expanded in Material, Fluent and Crystal themes

A possible workaround is to change the WindowCaptionHeight property:

 var parameters = SystemParameters2.Current;
 parameters.GetType().GetProperty("WindowCaptionHeight").SetValue(parameters, SystemParameters2.Current.WindowCaptionHeight + 26, null);

RadRibbonDropDownButton DropDownIndicator isn't rotated when the DropDownButtonPosition is Right and the DropDownPlacement is Right
Last Updated: 25 Nov 2019 09:20 by ADMIN
Release LIB 2019.3.1125

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 some cases an InvalidOperationException is thrown when the control is loaded too early (before it is added to the visual tree). This reproduces only when the ribbon's content is minimized initially.

To work this around, you can set the IsMinimizable property of RadRibbonView to False.

The ribbon tab doesn't get selec if you click in the exact middle of the header of RadRibbonTab.

To work this around, extract the ControlTemplate of RadRibbonTab and move the Grid with x:Name="ContentPanel" before the Grid with x:Name="HeaderPanel".
