ASP.NET 4 Unleashed

Working with Control Property Collections

When you build more complex controls, you often need to represent a collection of items. For example, the standard ASP.NET DropDownList control contains one or more ListItem controls that represent individual options in the DropDownList. The GridView control can contain one or more DataBoundField controls that represent particular columns to display.

In this section, we build several controls that represent a collection of items. We build multiple content rotator controls that randomly display HTML content, and a server-side tab control that renders a tabbed view of content.
