UIElement.CommandBindings Property

 

Gets a collection of CommandBinding objects associated with this element. A CommandBinding enables command handling for this element, and declares the linkage between a command, its events, and the handlers attached by this element.

Namespace:   System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

Public ReadOnly Property CommandBindings As CommandBindingCollection

Property Value

Type: System.Windows.Input.CommandBindingCollection

The collection of all CommandBinding objects.

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

<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.

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 In Detail.

The following example does essentially the same thing in code:

' Creating CommandBinding and attaching an Executed and CanExecute handler
Dim OpenCmdBinding As New CommandBinding(ApplicationCommands.Open, AddressOf OpenCmdExecuted, AddressOf OpenCmdCanExecute)

Me.CommandBindings.Add(OpenCmdBinding)
