Repeater嵌套绑定Repeater

C#:

private void RpTypeBind()
        {//GetQuestionTypeAndCount() 返回一个datatable
            this.rptypelist.DataSource = LiftQuestionCtr.GetQuestionTypeAndCount();                   
            this.rptypelist.DataBind();
        }
               protected void rptypelist_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("rpquestionlist") 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 typeid = Convert.ToInt32(rowv["qtid"]); //获取填充子类的id 
                rep.DataSource = LiftQuestionCtr.GetSomeQuestionsByTypeid(typeid, 2);
                rep.DataBind();
            }
        }

 

aspx:

<table border="0" cellpadding="0" cellspacing="0" style="margin-bottom: 5px" width="100%">
    <asp:Repeater runat="server" ID="rptypelist" OnItemDataBound="rptypelist_ItemDataBound">
        <ItemTemplate>
            <tr>
                <td class="fb">
                    &nbsp;&nbsp;<a href="Lists.aspx?Qtid=<%#Eval("qtid") %>"><%#Eval("qtypename") %>a> <span id="askCount_15"
                        class="date2">[<%#Eval("typecount")%>]span>
                td>
            tr>
            <tr>
                <td>
                    <div id="askTop2_15" class="ask_list">
                        <asp:Repeater runat="server" ID="rpquestionlist">
                            <ItemTemplate>
                                <a href="Question.aspx?qid=<%#Eval("liftquestionid")%>">
                                    <%#Eval("questiontitle")%>a><br />
                            ItemTemplate>
                        asp:Repeater>
                    div>
                td>
            tr>
        ItemTemplate>
    asp:Repeater>
table>

如果绑定的是对象Model:

 protected void rptHomeHelpCategory_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater rptHomeHelp = (Repeater)e.Item.FindControl("rptHomeHelp");
                //找到分类Repeater关联的数据项
                HiddenField hd_CategoryId = e.Item.FindControl("hd_CategoryId") as HiddenField;
                //提取分类ID
                //int CategorieId = Convert.ToInt32(hd_CategoryId.Value);
                var helpCategoryInfo = e.Item.DataItem as HelpCategoryInfo;//找到分类Repeater关联的数据项 
                if (helpCategoryInfo != null)
                {
                    int CategorieId = helpCategoryInfo.CategoryID; //获取填充子类的id 
                    //根据分类ID查询该分类下的产品，并绑定产品Repeater
                    string filter = " IsToHome=1 and categoryid =" + CategorieId + " ";
                    string argument = string.Empty;
                    string value = string.Empty;
                    string order = "[helpId],[TopLevel] desc";
                    int totalRecords = 0;

                    IHelp dal = Factory.Create("Help");
                    var data = dal.HelpList(filter, string.Empty, string.Empty, order, 1, 100, out totalRecords);

                    if (data != null)
                    {
                        rptHomeHelp.DataSource = data;
                        rptHomeHelp.DataBind();
                    }
                }
            }
        }
