ASP.Net中数据展示控件的嵌套使用示例

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);}}
