Panel.AddAttributesToRender Method

Adds information about the background image, alignment, wrap, and direction to the list of attributes to render.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

protected override void AddAttributesToRender (
	HtmlTextWriter writer
)
protected void AddAttributesToRender (
	HtmlTextWriter writer
)
protected override function AddAttributesToRender (
	writer : HtmlTextWriter
)

Parameters

writer

An HtmlTextWriter that represents the output stream to render HTML content on the client.

The AddAttributesToRender method is used primarily by control developers.

The following code example demonstrates how to override the AddAttributesToRender method in a custom server control so that the Panel text always displays as bold.
