repeater可以嵌套么？

Question

repeater可以嵌套么？
比如列表显示几个品牌，每个品牌显示几个产品，用什么方法做比较好？
网上有提过用repeater嵌套，我未试过，现在也不想去试，不想看代码，可以的话请用中文解析。

Answer 1

可以嵌套！
假如有两个td
第一个td显示品牌
第二个td在放个repeater
显示产品

Answer 2

第二个reperter的数据源哪里来？用品牌ID再读一次数据库？

Answer 3

哦，那情有可原。
在外层repeater的绑定事件中找到外层主键的ID，搜索内层repeater，然后再绑定数据源。

Answer 4

可以
Repeater rpt = (Repeater)e.Item.FindControl("Repeater2");  

Answer 5

完全可以嵌套，还是有代码比较清晰。
 <asp:Repeater ID="rptTop" runat="server" OnItemDataBound="rptTop_ItemDataBound">                      
                           <SeparatorTemplate>
                            <br />
                           </SeparatorTemplate>
                           <ItemTemplate>
                           <img src="../img/RedDot.gif" />
                            <a href="SecendLeve.aspx?Id=<%#Eval("Id") %>&pId=<%= Request.QueryString["Id"].ToString()%>"><%#Eval("ClassName") %></a>
                            <div  style="margin:0px 0px 0px 30px">
                            <asp:Repeater ID="rptSecentContent" runat="server" >
                                <SeparatorTemplate>
                                    <br />
                                </SeparatorTemplate>
                                <ItemTemplate>
                                <img src="../img/pointD.jpg" alt="" />
                                    <a href="../Content/ThreeContent.aspx?ThreeId=<%#Eval("Id") %>&Id=<%=Request.QueryString["pId"].ToString() %>&pId=<%=Request.QueryString["Id"].ToString() %>">
                                    <%#Eval("Title").ToString().Length >8?Eval("Title").ToString().Remove(8)+"..." :Eval("Title") %></a>
                                </ItemTemplate>
                            </asp:Repeater>
                            </div>
                           </ItemTemplate>
                        <FooterTemplate>
                        
                        </FooterTemplate>
                    </asp:Repeater>

Answer 6

repeater被解析为div，而div是肯定可以嵌套的

Answer 7

Repeater嵌套实例（完整）

Answer 8

可以 在第一个绑定的时候给第二个repeater 指定数据源就行了

        protected void rptheme_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType==ListItemType.Item)
            {
                Repeater InnerRepeat = e.Item.FindControl("rpimage") as Repeater;
                DataRowView Dr = (DataRowView)e.Item.DataItem;
                string rpID = Dr["ID"].ToString();
                Ds2.Tables[0].DefaultView.RowFilter = "CID=" + rpID;                SnowWolf.OleDBSqlHelper.OleDBSqlHelper Mycm = new SnowWolf.OleDBSqlHelper.OleDBSqlHelper();
                string Sqlstr = "select [ID],[CID],[ImageName],[Title] from [V_Theme_Image] where [CID] in(@CID)";
                System.Data.OleDb.OleDbParameter[] Param = new System.Data.OleDb.OleDbParameter[1];
                Param[0] = new System.Data.OleDb.OleDbParameter("@CID", Convert.ToInt32(rpID));
                DataSet Ds = Mycm.AccessDataSet(Sqlstr, Param);
                Mycm.Dispose();                InnerRepeat.DataSource = Ds;
                InnerRepeat.DataBind();
            }
        }<asp:Repeater ID="rptheme" runat="server" OnItemDataBound="rptheme_ItemDataBound">
                            <ItemTemplate>
                                <li>
                                    <div class="pic">
                                        <a href="javascript:CreateOverlay(<%# DataBinder.Eval(Container.DataItem, "ID")%>)"
                                            >
                                            <img src="image/theme/<%# DataBinder.Eval(Container.DataItem, "ImageName")%>" alt=""
                                                width="221" height="141"></a></div>
                                    <div class="caseText">
                                        <p>
                                            <%# DataBinder.Eval(Container.DataItem, "Title")%></p>
                                    </div>
                                </li>
                                <div style="display: none;" class="work<%# DataBinder.Eval(Container.DataItem, "ID")%>">
                                    <asp:Repeater ID="rpimage" runat="server">
                                        <ItemTemplate>
                                            <a href="image/theme/<%# DataBinder.Eval(Container.DataItem, "CID")%>/<%# DataBinder.Eval(Container.DataItem, "ImageName")%>"
                                                title="<%# DataBinder.Eval(Container.DataItem, "Title")%>" class="pirobox_gall_work<%# DataBinder.Eval(Container.DataItem, "CID")%>">
                                            </a>
                                        </ItemTemplate>
                                    </asp:Repeater>
                                </div>
                            </ItemTemplate>
                        </asp:Repeater>不知道为什么，只是第一个绑定了里面的repeater，后面的没有绑定。

Answer 10

建议用个隐藏域HiddenField保存父级的id
使用的时候
 HiddenField hd = e.Item.FindControl("hdfID") as HiddenField;
int id= Convert.ToInt32(hd.Value.ToString());
然后用这个id作为绑定子级Repeater的条件
