Image.RenderContents Method
.NET Framework 2.0
Renders the image control contents to the specified writer.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Assembly: System.Web (in system.web.dll)
protected void RenderContents ( HtmlTextWriter writer )
protected internal override function RenderContents ( writer : HtmlTextWriter )
Parameters
- writer
An HtmlTextWriter that represents the output stream to render HTML content on the client.
The RenderContents method is primarily used by control developers. The Image control implements the RenderContents method to skip rendering of any child controls.
The following code example demonstrates how to override the RenderContents method in a custom server control so that some text is always displayed after the Image.
