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
System.ComponentModel.ErrorsChangedEventManager
| 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.) |
