| 标题 | asp.net中数据展示控件的嵌套使用示例 |
| 范文 | 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); } } |
