11. ASP.Net Repeater Control The Repeater is a basic templated data-bound list typically used to display records from a: –Database table –Collections such as arraylist containing objects. 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.

12. 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.

13. 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:\salesDB.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

14. Note: Databinding tag

15. 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.

16. Creating a Table Using Repeater (DataSource can be a Readaer or Dataset) Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = c:\salesDB.mdb" Dim objConn As New OleDbConnection(strConn) Dim strSQL As String = "select * from customer;" Dim objComm As New OleDbCommand(strSQL, objConn) Dim Results As String objConn.Open() Dim objDataReader As OleDbDataReader objDataReader = objComm.ExecuteReader() Repeater1.DataSource = objDataReader Repeater1.DataBind() objDataReader.Close() or 'OleDbDataAdapter1.Fill(DataSet21) 'Repeater1.DataSource = DataSet21 'Repeater1.DataMember = "customer" 'Repeater1.DataBind()

17. Creating a Table Using Repeater CID Cname City Rating

18. Repeater Binding To An ArrayList myCust.getData("C01") myCust.getOrders("C01") Repeater1.DataSource = myCust.orders Repeater1.DataBind()

19. Binding to Object’s Properties

20. Creating Links Using Repeater 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:\salesDB.mdb" Dim objConn As New OledbConnection(strConn) Dim strSQL As String = "select * from product;" Dim objComm As New OleDbCommand(strSQL, objConn) objConn.Open() Dim objDataReader As OleDbDataReader objDataReader = objComm.ExecuteReader() Repeater1.DataSource = objDataReader Repeater1.DataBind() objConn.Close() End Sub
