If you want to set a class for each row, and you need a data identifier, then your best approach is to process it, since each row is bound:

 <asp:Repeater ID="Repeater1" runat="server" DataSourceID="dsInbox" OnItemDataBound="Repeater1_ItemDataBound">

and in code:

 protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) { if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) { MyType myItem = (MyType)e.Item.DataItem; var dataId = myItem.DataId; // Do whatever you need here. } }
