解决方案 »

  1.   

    Repeater Repeater2= (Repeater)e.Item.Parent;
    在Command里这么写，不难
      

  2.   


    protected void RpFirst_ItemDataBound(object sender, RepeaterItemEventArgs e)
            {
                //判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，
                //HeaderTemplate，，ItemTemplate，SeparatorTemplate）
                if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
                {
                    Repeater rep = e.Item.FindControl("RpSecondMenu") as Repeater;//找到里层的repeater对象
                    DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项 
                    int fatherID = Convert.ToInt32(rowv["FatherID"]); //获取填充子类的id 
                    Maticsoft.BLL.YZ_MenuInfo bll = new Maticsoft.BLL.YZ_MenuInfo();
                    rep.DataSource = bll.getSecondMenuListByFatherID(fatherID);
                    rep.DataBind();
                }        }
    把里面该改的改成你项目对应的就可以了
      

  3.   

    <asp:Label ID="Label1" runat="server" Text='<%#Eval("UserID")%>'></asp:Label> <br />
      <asp:Repeater ID="Repeater2" runat="server" DataSource='<%# GetDetails(Convert.ToInt32(Eval("ID"))) %>'>  
    添加按钮
    protected void Button1_Click(object sender, EventArgs e)
            {
                RepeaterItem item  =(RepeaterItem) ((Button)sender).Parent;
                Label l = (Label)item.FindControl("lbl");
                Response.Write(l.Text);
            }

    你怎么会在Repeater2的Item里面找Repeater2的呢？
    Repeater2不是在Repeater1的Item里面么？
    我看不懂了。这个代码。
