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);
}
}
