asp.net中數據展示控件的嵌套使用

1，工作中遇到這樣一個需求，頁面上要把所有的User加載出來，同時每個User后面緊跟著要把User的任務加載出來！我的處理方法是用Repeater來加載所有的User，同時在Repeater里面嵌套一個GridView，將每個User的任務展示出來！代碼如下

前臺代碼：

<asp:Repeater ID="Repeater1" runat="server"         onitemdatabound="Repeater1_ItemDataBound">        <HeaderTemplate>            <table border="0" cellspacing="0" cellpadding="0" width="100%">            <tr>        </HeaderTemplate>            <ItemTemplate>                <td class="list_table_in">                                        <span class="leaderTitle">高管：<a href='/LeaderSchedule/_layouts/LS/LeaderDetail.aspx?loginName=<%#Eval("LoginName") %>'><%#Eval("UserName") %></a></span><asp:GridView ID="gv_InRep" runat="server" AutoGenerateColumns="False" AllowSorting="True"                        OnRowCreated="GV_DoneList_RowCreated" OnSorting="GV_DoneList_Sorting" AllowPaging="True"                        CSSClass="tasklisttbl" Width="100%" OnRowDataBound="GV_DoneList_RowDataBound"                        EnableModelValidation="True">                        <AlternatingRowStyle BackColor="#FDFEFF" />                        <HeaderStyle HorizontalAlign="Center" ForeColor="Black" Height="20" />                        <RowStyle HorizontalAlign="Center" Height="26px" />                        <Columns>                            <asp:BoundField HeaderText="日期" ItemStyle-CssClass="custom" DataField="Date" SortExView Code
后臺代碼：
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)        {            try            {                if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)                {                    GridView gv = e.Item.FindControl("gv_InRep") as GridView;//找到里層的repeater對象                    Leader rowv = (Leader)e.Item.DataItem;//找到分類Repeater關聯的數據項                     string typeid = rowv.LoginName; //獲取填充子類的id                     SetSorting();                    gv.DataSource = PointDataSource(typeid);                    gv.DataBind();                                    }            }            catch (Exception ex)            {                SysLog syslog = new SysLog();                syslog.ListName = ConstData.ListName_PCITC_LS_Schedule;                syslog.LType = "Repeater的Item綁定事件異常";                syslog.WorkFlowName = "領導日程管理系統";                syslog.Location = "Repeater綁定數據：OtherSchedule.aspx";                syslog.Message = "頁面信息加載異常：" + ex.Message;                syslog.DataSource = 0;                logprovider.AddAuditRecordToSource(syslog);            }        }
