LinkButton.AddAttributesToRender Method

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Adds the attributes of the LinkButton control to the output stream for rendering on the client.

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

protected override void AddAttributesToRender(
	HtmlTextWriter writer
)

Parameters

writer
Type: System.Web.UI.HtmlTextWriter

A System.Web.UI.HtmlTextWriter that contains the output stream to render on the client.

The following code example demonstrates how to override the AddAttributesToRender method in a custom server control, so that the LinkButton list item text always appears bold.
