UIElement.CommandBindings Property

Gets a collection of CommandBinding objects associated with this element.

Namespace: System.Windows
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public:
property CommandBindingCollection^ CommandBindings {
	CommandBindingCollection^ get ();
}
/** @property */
public CommandBindingCollection get_CommandBindings ()

public function get CommandBindings () : CommandBindingCollection

<object>
  <object.CommandBindings>
    oneOrMoreCommandBindings
  </object.CommandBindings>
</object>
 oneOrMoreCommandBindings  One or more CommandBinding elements. Each of these should have a Command attribute set to a known command, and attributes set for the CanExecute and Executed handler implementations. For more information see CommandBinding. 

Property Value

The collection of all CommandBinding objects.

A CommandBinding enables command handling of a specific command for this element, and declares the linkage between a command, its events, and the handlers attached by this element.

Another typical way to populate the CommandBindings collection is to use CommandManager methods programmatically.

The following example adds a CommandBinding to a window using markup. Note that in XAML, the CommandBindingCollection is not declared in the markup as an element; the collection object is inferred by the type that the property takes, and you populate the property element with one or more CommandBinding elements:

<Window.CommandBindings>
  <CommandBinding Command="ApplicationCommands.Open"
                  Executed="OpenCmdExecuted"
                  CanExecute="OpenCmdCanExecute"/>
</Window.CommandBindings>

For more information about the XAML syntax for collections, see XAML Syntax Terminology.

The following example does essentially the same thing in code:

// Creating CommandBinding and attaching an Executed and CanExecute handler
CommandBinding OpenCmdBinding = new CommandBinding(
    ApplicationCommands.Open,
    OpenCmdExecuted,
    OpenCmdCanExecute);

this.CommandBindings.Add(OpenCmdBinding);
