   <source lang="csharp">

list controls, tabular DataBound controls, and hierarchical DataBound controls. Working with List Controls ASP.NET 3.5 Framework includes the following five List controls: BulletedList: A bulleted list of items. 

             Each item can be displayed as text, a link button, or a hyperlink.

RadioButtonList: A list of radio buttons.

Use DetailsView and FormView to display a single data item at a time:

   <source lang="csharp">

DetailsView: Displays a single data item in an HTML table. 

            This control enables you to display, page, edit, and add data.

FormView: Uses a template to display a single data item. Unlike the DetailsView, a FormView enables you to layout a form by using templates.

Working with Tabular DataBound Controls

   <source lang="csharp">

There are six tabular DataBound controls. These controls can be divided into two types: those that display multiple data items at a time and those that display a single data item at a time. First, you can use any of the following controls to display a set of data items: GridView: A set of data items in an HTML table. 

         This control enables you to display, sort, page, select, and edit data.

DataList: A set of data items in an HTML table. 

         Unlike the GridView control, more than one data item can be displayed in a single row.

Repeater: Displays a set of data items using a template. 

         Repeater control does not automatically render an HTML table.

ListView: Displays a set of data items using a template. 

         ListView control supports sorting, paging, and editing database data.</source>
