ASP.Net Repeater Control The Repeater is a basic templated data-bound list. It has no built-in layout or styles, so you must explicitly declare all HTML layout, formatting, and style tags within the control's templates. The Repeater has no built-in editing support. The Repeater uses template to control formatting and data binding.

Repeater Control’s Templates Five types of templates: –HeaderTemplate, ItemTemplate, AlternatingItemTemplate, SeparatorTemplate, FooterTemplate Note 1: A Repeater binds its ItemTemplate and AlternatingItemTemplate to a DataSource. The HeaderTemplate, FooterTemplate, and SeparatorTemplate are not data-bound. Note 2: At a minimum, every Repeater must define an ItemTemplate.

Creating a Table Using Repeater To create a table using templates, include the begin table tag in the HeaderTemplate, a single table row tag and in the ItemTemplate, and the end table tag ( ) in the FooterTemplate.

Repeater Example Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Put user code to initialize the page here Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = c:\sales2k.mdb" Dim objConn As New OledbConnection(strConn) Dim strSQL As String = "select * from customer;" Dim objComm As New OleDbCommand(strSQL, objConn) objConn.Open() Dim objDataReader As OleDbDataReader objDataReader = objComm.ExecuteReader() Repeater1.DataSource = objDataReader Repeater1.DataBind() End Sub

Note: Databinding tag
