RepeaterItem.ItemIndex Property
Assembly: System.Web (in system.web.dll)
Use the ItemIndex property to determine the index number of the item in the Repeater control from the Items collection of the control.
 Note |
|---|
| This property only applies to data items in the Repeater control. The ItemType property must be set to ListItemType.Item, ListItemType.AlternatingItem, ListItemType.SelectedItem, or ListItemType.EditItem. |
The following example demonstrates how to use the ItemIndex property to display the index number of the item in the Repeater control from the Items collection of the control.
<%@ Page Language="C#" AutoEventWireup="True" %> <%@ Import Namespace="System.Data" %> <html> <head> <script language="C#" runat="server"> void Page_Load(Object Sender, EventArgs e) { if (!IsPostBack) { ArrayList values = new ArrayList(); values.Add(new PositionData("Item 1", "$6.00")); values.Add(new PositionData("Item 2", "$7.48")); values.Add(new PositionData("Item 3", "$9.96")); Repeater1.DataSource = values; Repeater1.DataBind(); } } void Button_Click(Object Sender, EventArgs e) { Label1.Text = "The Items collection contains: <br>"; foreach(RepeaterItem item in Repeater1.Items) { Label1.Text += item.ItemIndex.ToString() + " - " + ((DataBoundLiteralControl)item.Controls[1]).Text + "<br>"; } } public class PositionData { private string item; private string price; public PositionData(string item, string price) { this.item = item; this.price = price; } public string Item { get { return item; } } public string Price { get { return price; } } } </script> </head> <body> <form runat=server> <h3>Repeater Example</h3> <p> <asp:Repeater id="Repeater1" runat="server"> <HeaderTemplate> <table border=1> <tr> <td><b>Item</b></td> <td><b>Price</b></td> </tr> </HeaderTemplate> <ItemTemplate> <tr> <td> <%# DataBinder.Eval(Container.DataItem, "Item") %> </td> <td> <%# DataBinder.Eval(Container.DataItem, "Price") %> </td> </tr> </ItemTemplate> <FooterTemplate> </table> </FooterTemplate> </asp:Repeater> <p> <asp:Button id="Button1" Text="Display Items in Repeater" OnClick="Button_Click" runat="server"/> <br><br> <asp:Label id="Label1" runat="server"/> </form> </body> </html>
