RegisterClassCommandBinding Method (CommandManager)

Visual Basic (Declaration)
Visual Basic (Usage)
C#
C++/CLI

Public Shared Sub RegisterClassCommandBinding( _
   ByVal type As Type, _
   ByVal commandBinding As CommandBinding _
)

Dim type As Type
Dim commandBinding As CommandBinding
 
CommandManager.RegisterClassCommandBinding(type, commandBinding)

public static void RegisterClassCommandBinding( 
   Type type,
   CommandBinding commandBinding
)

public:
static void RegisterClassCommandBinding( 
   Type^ type,
   CommandBinding^ commandBinding
)

Parameters

type: The class with which to register commandBinding.
commandBinding: The command binding to register.

In addition to instance command binding, the commanding framework in ClientUI also supports class command binding API which is available in the CommandManager class. The class command binding is particularly useful when you have a fairly large amount of commands to bind to the controls.

The following code example shows how to use class command binding API to register a routed command on a specific type rather than an instance.

using System.Windows; using ClientUIApplication_Docs.Commands; using Intersoft.Client.Framework.Input; using Intersoft.Client.UI.Navigation; namespace ClientUIApplication_Docs.RoutedCommands { public partial class ClassCommandBinding : UXPage { public ClassCommandBinding() { // It is important to initialize the static EditingCommands class // before InitializeComponent is called EditingCommands.Initialize(); InitializeComponent(); } static ClassCommandBinding() { RoutedUICommand[] commands = new RoutedUICommand[] { EditingCommands.Cut, EditingCommands.Copy, EditingCommands.Paste }; // register class-level command binding for RoutedUICommand foreach (RoutedUICommand command in commands) { CommandManager.RegisterClassCommandBinding( typeof(UXPage), new CommandBinding(command, OnCommandExecuted, OnCanExecute)); } } private static void OnCanExecute(object sender, CanExecuteRoutedEventArgs e) { e.CanExecute = true; } private static void OnCommandExecuted(object sender, ExecutedRoutedEventArgs e) { string command = ((RoutedCommand)e.Command).Name; string target = ((FrameworkElement)e.OriginalSource).Name; MessageBox.Show("The " + command + " command has been invoked on target object " + target); } } }
