function Leadtools.Controls.ImageViewer.onPropertyChanged( propertyName )
Parameter | Type | Description |
---|---|---|
propertyName | string | The property name. |
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.
