BindEvent() public method

public BindEvent ( DependencyObject owner, string eventName ) : void
owner	System.Windows.DependencyObject
eventName	string
return	void

Example #1

        /// <summary>
        /// Handles changes to the Event property.
        /// </summary>
        private static void OnEventChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            CommandBehaviorBinding binding = FetchOrCreateBinding(d);

            //check if the Event is set. If yes we need to rebind the Command to the new event and unregister the old one
            if (binding.Event != null && binding.Owner != null)
            {
                binding.Dispose();
            }
            //bind the new event to the command
            binding.BindEvent(d, e.NewValue.ToString());
        }
