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);

}

}
