Properties

Dispatcher	Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject)
Item[Object]	Gets or sets the data being stored for the specified source. (Inherited from WeakEventManager)
ReadLock	Establishes a read-lock on the underlying data table, and returns an IDisposable. (Inherited from WeakEventManager)
WriteLock	Establishes a write-lock on the underlying data table, and returns an IDisposable. (Inherited from WeakEventManager)

Methods

AddHandler(ICommand, EventHandler<EventArgs>)	Adds the specified delegate as an event handler of the specified source.
CheckAccess()	Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject)
DeliverEvent(Object, EventArgs)	Delivers the event being managed to each listener. (Inherited from WeakEventManager)
DeliverEventToList(Object, EventArgs, WeakEventManager+ListenerList)	Delivers the event being managed to each listener in the provided list. (Inherited from WeakEventManager)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
NewListenerList()	Returns a new object to contain listeners to an event. (Inherited from WeakEventManager)
ProtectedAddHandler(Object, Delegate)	Adds the specified delegate as an event handler of the specified source. (Inherited from WeakEventManager)
ProtectedAddListener(Object, IWeakEventListener)	Adds the provided listener to the provided source for the event being managed. (Inherited from WeakEventManager)
ProtectedRemoveHandler(Object, Delegate)	Removes the previously added handler from the specified source. (Inherited from WeakEventManager)
ProtectedRemoveListener(Object, IWeakEventListener)	Removes a previously added listener from the provided source. (Inherited from WeakEventManager)
Purge(Object, Object, Boolean)	Removes inactive listener entries from the data list for the provided source.
Remove(Object)	Removes all listeners for the specified source. (Inherited from WeakEventManager)
RemoveHandler(ICommand, EventHandler<EventArgs>)	Removes the specified event handler from the specified source.
ScheduleCleanup()	Requests that a purge of unused entries in the underlying listener list be performed on a lower priority thread. (Inherited from WeakEventManager)
StartListening(Object)	Begins listening for the CanExecuteChanged event on the specified source.
StopListening(Object)	Stops listening for the CanExecuteChanged event on the specified source.
ToString()	Returns a string that represents the current object. (Inherited from Object)
VerifyAccess()	Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject)
