Office 2016 has a search field in the ribbon for quick access to commands that may be hard to find.
Can such functionality be added to the telerik ribbon ?

Declined: We consider this functionality to be an Application logic as the information that need to be displayed is based on the UI(the defined options/buttons in the RibbonView). Also the keywords for activating a given option may be different based on client preferences or language. This functionality can easily be achieved with a custom Style for the RadRibbonTab, containing only the control which you will use for the search (RadAutoCompleteTextBlock/RadWatermarkTextBox e.t.).

Workaround:
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()
{
    InitializeComponent();
    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);
}

Workaround for this bug is setting Style.Triggers for this scenario.

<Style BasedOn="{StaticResource RadRibbonSplitButtonStyle}" TargetType="telerik:RadRibbonSplitButton">
  <Style.Triggers>
    <MultiTrigger>
      <MultiTrigger.Conditions>
        <Condition Property="IsChecked" Value="True"/>
        <Condition Property="IsEnabled" Value="True"/>
        <Condition Property="CurrentSize" Value="Medium"/>
      </MultiTrigger.Conditions>
      <MultiTrigger.Setters>
        <Setter Property="Foreground" Value="{DynamicResource CheckedBrush}"/>
      </MultiTrigger.Setters>
    </MultiTrigger>
  </Style.Triggers>
</Style>

The KeyboardNavigation throws null reference exception when you try to move through the DropDownButton of the QAT and we does not have the button in the style targeting the QAT.

The designer of VS crashes with a "Key cannot be null" when custom markup extension is used in Style Setter. This reproduces in the sample app attached in the blog (http://www.telerik.com/blogs/bring-office-2016-inspired-style-to-your-app-with-ui-for-wpf) on the TextBlock of the RabRadioButton HeadingStyle (snapshot attached) if you open MainWindow in Designer. Runtime everything works as expected.

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;
}

Reproduces when you add the ContextualGroups in code-behind. While resizing the RibbonWindow the Ribbon Title overlaps the ContextualGroup Header.

Possible workaround is to set the ApplicationButtonVisibility property to Hidden.

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

The default size is 9. If you change it the issue occurs. This brings a visual glitch in the window. The title text is resized but the titlebar is not.

Note: This is reproducible only if the DPI is larger than 100%.

To work this around manually set the size of the titlebar element.

private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
    Grid windowDecorator = this.ChildrenOfType<Grid>().FirstOrDefault(x => x.Name =="MaximizeWindowDecorator");
    RibbonTitleBarPanel ribbonTitlePanel = this.ChildrenOfType<RibbonTitleBarPanel>().FirstOrDefault(x => x.Name == "RibbonTitleBarPanel");
    windowDecorator.RowDefinitions[0].Height = newGridLength(ribbonTitlePanel.ActualHeight);
}

Currently, RadRibbonView's OnApplyTemplate method can be called after adding the new tabs so that the group and tabs are redrawn correctly.
