Leadtools.Annotations.Core Namespace > AnnSnapToGridOptions Class : OnPropertyChanged Method |
public virtual void OnPropertyChanged( AnnPropertyChangedEventArgs e )
'Declaration
Public Overridable Sub OnPropertyChanged( _ ByVal e As AnnPropertyChangedEventArgs _ )
public virtual void OnPropertyChanged( AnnPropertyChangedEventArgs e )
public void onPropertyChanged(AnnPropertyChangedEvent event)
function Leadtools.Annotations.Core.AnnSnapToGridOptions.OnPropertyChanged( e )
Raising an event invokes the event handler through a function. The OnPropertyChanged method also allows derived classes to handle the event without attaching a function to the event. 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.
