asp.net中数据展示控件的嵌套使用

1，工作中遇到这样一个需求，页面上要把所有的User加载出来，同时每个User后面紧跟着要把User的任务加载出来！我的处理方法是用Repeater来加载所有的User，同时在Repeater里面嵌套一个GridView，将每个User的任务展示出来！代码如下

前台代码：

<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" SortExPRession="Date">                                <ItemStyle Width="15%" />                            </asp:BoundField>                            <asp:BoundField HeaderText="时间" DataField="Time" SortExpression="Time">                                <ItemStyle Width="11%" />                            </asp:BoundField>                            <asp:BoundField HeaderText="工作安排" DataField="WorkPlan" SortExpression="WorkPlan">                                <ItemStyle Width="11%" />                            </asp:BoundField>                            <asp:BoundField HeaderText="地点" DataField="Place" SortExpression="Place">                                <ItemStyle Width="11%" />                            </asp:BoundField>                        </Columns>                        <PagerTemplate>                        </PagerTemplate>                    </asp:GridView>                </td>                <asp:Literal ID="Literal1" runat="server" Text='<%#Eval("Flag") %>'></asp:Literal>            </ItemTemplate>        <FooterTemplate>            </tr></table>        </FooterTemplate>    </asp:Repeater>

后台代码：

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;//找到里层的repeater对象                    Leader rowv = (Leader)e.Item.DataItem;//找到分类Repeater关联的数据项                     string typeid = rowv.LoginName; //获取填充子类的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绑定事件异常";                syslog.WorkFlowName = "领导日程管理系统";                syslog.Location = "Repeater绑定数据：OtherSchedule.aspx";                syslog.Message = "页面信息加载异常：" + ex.Message;                syslog.DataSource = 0;                logprovider.AddAuditRecordToSource(syslog);            }        }
