Description

How to close the active pane with a key combination.

Solution

As of R3 2020, you can use the new ClosePane command to close the currently active pane. The command accepts a parameter of type ClosePaneMode which has three possible values:

• DocumentPanes: The active document pane is closed or if there is no active, the first selected document pane is closed.
• NonDocumentPanes: The active non-document pane is closed, if any.
• ActivePanes: The active pane is closed, if any.

If no parameter is passed, the command will close the currently active pane, if there is such.

Example 1: Binding the ClosePane to Ctrl+F4 for a single RadDocking instance

• XAML

<telerik:RadDocking> 
    <!-- ... --> 
    <telerik:RadDocking.InputBindings> 
        <KeyBinding Command="telerik:RadDockingCommands.ClosePane" CommandParameter="DocumentPanes" Key="F4" Modifiers="Ctrl" /> 
    </telerik:RadDocking.InputBindings> 
</telerik:RadDocking> 

You can also bind the command for all RadDocking controls in your application by using the CommandManager.RegisterClassInputBinding method.

Example 2: Binding the ClosePane to Ctrl+F4 for all RadDocking controls in the application

• C#

public App() 
{ 
    KeyBinding keyBinding = new KeyBinding(RadDockingCommands.ClosePane, new KeyGesture(Key.F4, ModifierKeys.Control)) { CommandParameter = ClosePaneMode.DocumentPanes }; 
    CommandManager.RegisterClassInputBinding(typeof(RadDocking), keyBinding); 
}
