onPropertyChanged Method

Summary

Raises the PropertyChanged event.

Syntax
TypeScript

ImageViewer.prototype.onPropertyChanged = function( 
   propertyName 
) 
onPropertyChanged( 
   propertyName: string 
): void; // protected 

Parameters

propertyName

The property name.

Remarks

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.
