Repeater嵌套（灵活的）

页面代码

<form id="form1" runat="server">

    <asp:Repeater ID="rptCategories" runat="server" OnItemCommand="rptCategories_ItemCommand">

        <HeaderTemplate>

            <table width="100%" border="1" cellspacing="0" cellpadding="0">

        </HeaderTemplate>

        <ItemTemplate>

            <!--分类名称-->

            <tr>

                <th>

                    <asp:LinkButton ID="LinkButton1" CommandName='<%#DataBinder.Eval(Container.DataItem, "ID") %>'

                        runat="server"><%#DataBinder.Eval(Container.DataItem, "ID")%></asp:LinkButton>

                        <input type="button" value="收" onclick="aa()" />

                </th>

                <th>

                   <label runat="server" id="lbl"> <%# DataBinder.Eval(Container.DataItem, "loginid")%></label>

                </th>

            </tr>

            <!--分类下的产品-->

            <asp:Repeater ID="rptProduct" runat="server">

                <ItemTemplate>

                    <tr>

                        <td>

                            <%# DataBinder.Eval(Container.DataItem, "Course")%>

                        </td>

                        <td>

                            <%# DataBinder.Eval(Container.DataItem, "Score")%>

                        </td>

                    </tr>

                </ItemTemplate>

            </asp:Repeater>

        </ItemTemplate>

        <FooterTemplate>

            </table>

        </FooterTemplate>

    </asp:Repeater>

    </form>

根据点击Repeater上的按钮，在这行下方嵌套Repeater

 protected void rptCategories_ItemCommand(object source, RepeaterCommandEventArgs e)

        {

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

            {

                Repeater rptProduct = (Repeater)e.Item.FindControl("rptProduct");

                //找到分类Repeater关联的数据项

                DataRowView rowv = (DataRowView)e.Item.DataItem;

                var a = e.Item.Controls[];

                //提取分类ID

                string id = e.CommandName;

                //string CategorieId = Convert.ToString(rowv["Name"]);

                //int CategorieId = Convert.ToInt32(rowv["ID"]);

                //根据分类ID查询该分类下的产品，并绑定产品Repeater

                List<Student> list = new List<Student>();

                Student stu = new Student() { Course = "语文", Score =  };

                list.Add(stu);

                list.Add(new Student() { Course = "数学", Score =  });

                //绑定嵌套数据

                rptProduct.DataSource = list;

                rptProduct.DataBind();

            }

        }

绑定原数据

protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                if (!IsPostBack)

                {

                    List<Student> list = new List<Student>();

                    Student stu = new Student() { ID = , Name = "赵六", Sex = "男", Phone = "" };

                    list.Add(stu);

                    list.Add(new Student() { ID = , Name = "王五", Sex = "男", Phone = "136*******8382" });

                    list.Add(new Student() { ID = , Name = "卡琳", Sex = "女", Phone = "138*******9083" });

                    list.Add(new Student() { ID = , Name = "王五", Sex = "男", Phone = "157*******7002" });

                    DataTable dt = new DataTable();

                    DataSet ds = GetDataSet("select * from profile");

                    rptCategories.DataSource = (DataTable)ds.Tables[];

                    rptCategories.DataBind();

                }

            }

        }
