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);
}
}
