ErrorsChangedEventManager Class
Provides a WeakEventManager implementation so that you can use the weak event listener pattern to attach listeners for the ErrorsChanged event.
Assembly: WindowsBase (in WindowsBase.dll)
System.Windows.Threading::DispatcherObject
System.Windows::WeakEventManager

| Name | Description | |
|---|---|---|
 | 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 anIDisposable.(Inherited from WeakEventManager.) |
| Name | Description | |
|---|---|---|
  | AddHandler(INotifyDataErrorInfo^, EventHandler<DataErrorsChangedEventArgs^>^) | Adds the specified event handler, which is called when specified source raises the ErrorsChanged event. |
| 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.) |
| Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
| GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
| GetType() | |
| MemberwiseClone() | |
| NewListenerList() | Returns a new object to contain listeners to the ErrorsChanged event.(Overrides WeakEventManager::NewListenerList().) |
| 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. Returns true if some entries were actually removed from the list.(Inherited from WeakEventManager.) |
| Remove(Object^) | Removes all listeners for the specified source.(Inherited from WeakEventManager.) |
| RemoveHandler(INotifyDataErrorInfo^, EventHandler<DataErrorsChangedEventArgs^>^) | 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 ErrorsChanged event on the specified source.(Overrides WeakEventManager::StartListening(Object^).) |
| StopListening(Object^) | Stops listening for the ErrorsChanged event on the specified source.(Overrides WeakEventManager::StopListening(Object^).) |
| 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.) |
