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.

No code example is currently available or this language may not be supported.
