One of important goals of any application development process is making data presentation richer. ASP.NET 2.0 provides many server controls which render data in different rich formats and styles. For example, DataGrid control is suitable in many scenarios where you wish to display data in a grid like representation for easy understanding. Similarly, if the situation demands for rendering list like data, you can consider using of DataLists and Repeater server controls.

Repeater control is a container control which is template based with no basic rendering of its own. This way, you define layout for the Repeater control by creating different templates based on your needs. You can create different kinds of lists using Repeater control including Table, Comma-separated list and XML formatted list.
Repeater Control Templates
Repeater controls provides different kinds of templates which helps in determining the layout of control's content. Templates generate markup which determine final layout of content.

Repeater control is an iterative control in the sense it loops each record in the DataSource and renders the specified template (ItemTemplate) for each record in the DataSource collection. In addition, before and after processing the data items, the Repeater emits some markup for the header and the footer of the resulting structure

Repeater control supports five templates which are as follows:

ItemTemplate

AlternatingItemTemplate

HeaderTemplate

FooterTemplate

SeparatorTemplate

ItemTemplate: ItemTemplate defines how the each item is rendered from data source collection.

AlternatingItemTemplate: AlternatingItemTemplates define the markup for each Item but for AlternatingItems in DataSource collection like different background color and styles.

HeaderTemplate: HeaderTemplate will emit markup for Header element for DataSource collection

FooterTemplate: FooterTemplate will emit markup for footer element for DataSource collection

SeparatorTemplate: SeparatorTemplate will determine separator element which separates each Item in Item collection. Usually, SeparateTemplate will be <br> html element or <hr> html element.

Add any Data Source control to the page such as sqlDataSource or AccessDataSource. Configure Data Source control such that you specify connection information and perform query.
