onPreRender Method

Summary

Raises the PreRender event.

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

Parameters

e

The event data.

Remarks

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