datalist数据绑定是时遇到的问题

Question

 protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
        {
            Repeater Repeater1;                       
                if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
                {
                    int liuyanid = Convert.ToInt32(DataBinder.Eval(e.Item.DataItem, "id"));
                    Repeater1 = e.Item.FindControl("Repeater1") as Repeater;
                    dv = NoticesManage.getreplybyliuyan(liuyanid).Tables[0].DefaultView;
                    Repeater1.DataSource = dv;
                    Repeater1.DataBind();
                }           
       }
请问这句话是干吗的？加与不加有什么区别？
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
