repeater嵌套

Question

现有一个repeater1里面嵌套了另一个repeater2怎么样repeater2绑定数据       说使用这程方法的repeater1_ItemDataBound  最好请不要说

Answer 1

用for循环呗？
for (int i = 0; i < Repeater1.Items.Count; i++)
｛
      Repeater xxName= Repeater1.Items[i].FindControl("Repeater2") as Repeater;
     xxName.DataBind()
｝

Answer 5

绑定父级repeater，用for或者foreach遍历，通过findcontrol方法找到子Repeater，绑定

Answer 6

循环拿不到repeater2 
我为了减少viewstatues

Answer 7

拿不到？repeater2为null？还是怎样？  你repeater1要有值才行哦！

Answer 8

嵌套DataList的，Repeater也类似

Answer 9

repeater1_ItemDataBound
这个绝对可以。
另外 楼主可以这样
最外层的 repeater 绑定dataset
然后 里面两个datatable 设置好外键关系。。

protected void RepeaterShopping_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater RepeaterProduct = (Repeater)e.Item.FindControl("RepeaterProduct");
                string SellMemberID = DataBinder.Eval(e.Item.DataItem, "SellMemberID").ToString();
                var ProductLinq = (from ShoppingCartEntity in this.ShoppingDetailList
                                   where ShoppingCartEntity.SellMemberID == SellMemberID
                                   select new { ProductID = ShoppingCartEntity.ProductID, UserName = ShoppingCartEntity.UserName, ProductImg = ShoppingCartEntity.ProductImg, ProductName = ShoppingCartEntity.ProductName, SellMemberID = ShoppingCartEntity.SellMemberID, ID = ID }
                                   ).Distinct();
                RepeaterProduct.DataSource = ProductLinq.ToList();
                RepeaterProduct.DataBind();
            }
        }

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e){
if(e.Item.ItemType==ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem){
 int id =Convert.ToInt32( ((DataRowView)e.Item.DataItem).Row["id"].ToString());//获得对应ID
// DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项 
//int id = Convert.ToInt32(rowv["id"]); //获取填充子类的id 
 DataList dl = (DataList)e.Item.FindControl("DataList1"); //找到DataList1控件
      if (id > 0 && dl != null) {
        string sql_p = "select * from TB_SmallClass where fid=" + id + " order by orderId";
                    sdr = obj.ExecuteReader(sql_p, null);
                    dl.DataSource = sdr;
                    dl.DataBind();
                    sdr.Close();
                }
            }
        }

Answer 12

这种事就记住FindControl方法

Answer 13

3.主从显示<asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate>
            <tr class="c1">
                <td><%#Eval("sort") %></td>
                <td><a href="http://www.cnblogs.com/shtml/view_cls1/ViewCls_<%#Eval("id") %>.shtml" target="_blank"><%#Eval("cls_name") %></a> <a href="./admin_cls2_add.aspx?alt=1&id=<%#Eval("id") %>">[添加二级分类]</a></td>

                <!--DataSource='<%#Eval("TwoTable") %>'直接这样也是可以的-->
                <ItemTemplate>
                    
                <tr class="c2" onmouseover="className='tdover2'" onmouseout="className='tdout2'">

                </asp:Repeater>
        </ItemTemplate>
    </asp:Repeater>后台代码DataSet Ds = new DataSet();
            Ds.Tables.Add(Pn163.com_BLL.BLL_cls1.cls1DataSet().Tables[0].Copy());
            Ds.Tables.Add(Pn163.com_BLL.BLL_cls2.cls2DataSet().Tables[0].Copy());
            Ds.Relations.Add("TwoTable",Ds.Tables["cls1"].Columns["id"], Ds.Tables["cls2"].Columns["cls1_code"]);
            Telesa.DataBind.ToBind(Repeater1, Ds);

Answer 14

repeater1_ItemDataBound  里  FindControl

Answer 15

for循环，动态创建repeater，拼装HTML语句

Answer 16

在外面repeater绑定数据之后，寻找绑定了数据的行里的另一个repeater，
再给里面repeater绑定数据源，不久可以了
