Leadtools.Controls Assembly > Leadtools.Controls Namespace > ImageViewer Class : OnPropertyChanged Method |
protected virtual void OnPropertyChanged( string propertyName )
'Declaration
Protected Overridable Sub OnPropertyChanged( _ ByVal propertyName As String _ )
Raising an event invokes the event handler through a delegate. The OnPropertyChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Note to Inheritors: When overriding OnPropertyChanged in a derived class, be sure to call the base class's OnPropertyChanged method so that registered delegates receive the event.
