OnPropertyChanged Method

 function Leadtools.Controls.ImageViewer.onPropertyChanged( 
   propertyName 
)

!MISSING Scrap '_RTJavaScript_Method_SYNTAX'!

Parameters

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.
