    #region 获取应用插件分类

        IList<ApplyClass> typelist = apply.GetDescApplyClass();
        Rep_AppClass.DataSource = typelist;
        Rep_AppClass.DataBind();
    }
    #endregion


    #region 应用分类信息列表

    ///  应用分类信息列表
    /// </summary>

    /// <param name="e"></param>
    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;
