OnPreRender Method

 function Leadtools.Controls.ImageViewer.onPreRender( 
   e 
)

Parameters

Parameter	Type	Description
e	ImageViewerRenderEventArgs	The event data.

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.
