== There are three main types of DataBound controls==



<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.
CheckBoxList: A list of check boxes.
Multiple check boxes in the list can be selected.
DropDownList: A drop-down list.
Only one item in the drop-down list can be selected.
ListBox: A list box.
only one item in the list can be selected or multiple items can be selected.
RadioButtonList: A list of radio buttons.
Only one radio button can be selected.
All five controls inherit from the same base ListControl class.

== 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>
