onRenderBackground Method

Summary

Raises the RenderBackground event.

Syntax
TypeScript
JavaScript
ImageViewer.prototype.onRenderBackground = function( 
   e 
) 
onRenderBackground( 
   e: ImageViewerRenderEventArgs 
): void; // protected 

Parameters

e

The event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnRenderBackground 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 OnRenderBackground in a derived class, be sure to call the base class's OnRenderBackground method so that registered delegates receive the event.
