        IList < ApplyClass >  typelist  =  apply.GetDescApplyClass();
        Rep_AppClass.DataSource  =  typelist;

     protected   void  Rep_AppClass_ItemDataBound( object  sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)

         if  (e.Item.ItemType  ==  ListItemType.Item  ||  e.Item.ItemType  ==  ListItemType.AlternatingItem)
        {
        
             string  NowApplyClassId  =  ((ApplyClass)e.Item.DataItem).ApplyClassId.ToString();
            Repeater Rep_AppInfo  =  (Repeater)e.Item.FindControl( " Rep_AppInfo " );

             if  (Rep_AppInfo  !=   null )
            {
                Predicate < Applications >  FindValue  =   delegate (Applications obj) {  return  obj.ApplyClassId  ==  NowApplyClassId; };
                List < Applications >  info  =  applylist.FindAll((c)  =>  {  return  c.ApplyClassId  ==  NowApplyClassId; });
                Rep_AppInfo.DataSource  =  info;
                Rep_AppInfo.DataBind();
            }
        }
    }
     #endregion

 ListItemType.AlternatingItem 要引用 System.Web.UI.WebControls

 如果你绑定的数据并非一个实体类，可以通过如下方式获取，

    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {

       Repeater Repeater3  =  (Repeater)e.Item.FindControl( " Repeater3 " );
        string  DatumArticleID  =  ((DataRowView)(e.Item.DataItem))[ " DatumArticleID " ].ToString();

        if (Rep_AppInfo != null)
            {
                Predicate<Applications> FindValue = delegate(Applications obj) { return obj.ApplyClassId == NowApplyClassId; };
                List<Applications> info = applylist.FindAll((c) => { return c.ApplyClassId == NowApplyClassId; });
                Rep_AppInfo.DataSource = info;
                Rep_AppInfo.DataBind();
            }
        }

 

 

//在HeaderTemplate中寻找Label1，默认为第0个

string s=((Label)Repeater1.Controls[0].FindControl("Label1")).Text;

//在FooterTemplate中寻找Label2，默认为最后一个

string s=((Label)Repeater1.Controls[Repeater1.Controls.Count - 1].FindControl("Label2")).Text;
