Table.AddAttributesToRender Method

Adds HTML attributes and styles that need to be rendered to the specified HtmlTextWriter.

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

protected override void AddAttributesToRender(
	HtmlTextWriter writer


Type: System.Web.UI.HtmlTextWriter
The output stream that renders HTML content to the client.

This method is used primarily by control developers to insert the appropriate attributes and styles into the HtmlTextWriter output stream for a Table control. This method overrides WebControl.AddAttributesToRender.

The following code example demonstrates how to override the AddAttributesToRender method in a custom server control to add an attribute to the Table.
