| 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 cellspacing="0" cellpadding="0"> <tr> </HeaderTemplate> <ItemTemplate> <td> <span>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); } } |
