PostRenderChild Method

Notifies a parent UIElement following the rendering of one of its children.

Syntax

Visual Basic

'Declaration
 
Protected Overridable Sub PostRenderChild( _
   ByVal sink As HtmlTextWriter, _
   ByVal child As UIElement _
) 

C#

protected virtual void PostRenderChild( 
   HtmlTextWriter sink,
   UIElement child
)

Parameters

sink

The sink into which to deposit additional markup as may be required.

child

The child UIElement that has just rendered.

Remarks

The base class implementation of this method does nothing. Inheritors may override this method to track information about the progress of the rendering, or follow the rendering of certain children with special rendering by the parent.

An example of when overriding PostRenderChild is necessary is if a parent containing this UIElement must render markup after every other child UIElement. In this example, the implementation provided by the subclass would need to maintain a counter, incrementing it as it receives each notification. On every second notice, the implementation could trigger special rendering code in the base class to produce this markup.
