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);
            }

        }
