ListBox.AddAttributesToRender Method
.NET Framework 2.0
This method supports the .NET Framework infrastructure and is not intended to be used directly from your code.
Adds name, size, multiple, and onchange to list of attributes to render.
Namespace: System.Web.UI.WebControlsAssembly: System.Web (in system.web.dll)
The following code example demonstrates how to override the AddAttributesToRender method in a custom server control, so that the ListBox list item text always displays as bold.
