System.Web.UI.WebControls Namespace   DataListItem Class

Returns the index of an item in a DataList control.

The property is read only with no default value.

Use the ItemIndex property to determine the index number of a DataListItem from the Items collection of a DataList control.

NOTE: This property only applies to data items in the DataList 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 determine the position of an item in a DataList control. The type of each item is displayed along with the item index.

foreach ( DataListItem item in myDataList.Items ) {
   msg.Text += "<br>" + item.ItemIndex + " " + item.ItemType;
}

dim item as DataListItem
for each item in myDataList.Items
   msg.Text &= "<br>" & item.ItemIndex & " " & item.ItemType
next
