Examples of nested use of data display controls in ASP. Net

1. When you encounter such a requirement at work, you need to load all the users on the page, and each User is followed by the task of loading the User! My solution is to use Repeater to load all users and nest a GridView in Repeater to display the tasks of each User! The Code is as follows:

Front-end code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

<Asp: Repeater ID = "Repeater1" runat = "server" Onitemdatabound = "repeaterincluitemdatabound"> <HeaderTemplate> <Table border = "0" cellspacing = "0" cellpadding = "0" width = "100%"> <Tr> </HeaderTemplate> <ItemTemplate> <Td class = "list_table_in"> <Span class = "leaderTitle"> executives: <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 = "Date" ItemStyle-CssClass = "custom" DataField = "Date" SortExpression = "Date"> & Lt; ItemStyle Width = "15% "/ </Asp: BoundField> <Asp: BoundField HeaderText = "Time" DataField = "Time" SortExpression = "Time"> & Lt; ItemStyle Width = "11% "/ </Asp: BoundField> <Asp: BoundField HeaderText = "Work Arrangement" DataField = "WorkPlan" SortExpression = "WorkPlan"> & Lt; ItemStyle Width = "11% "/ </Asp: BoundField> <Asp: BoundField HeaderText = "location" 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>

Background code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

Protected void repeaterincluitemdatabound (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; // locate the repeater object in the layer Leader rowv = (Leader) e. Item. DataItem; // locate the data Item associated with the Repeater category String typeid = rowv. LoginName; // obtain the id of the fill subclass. SetSorting (); Gv. DataSource = PointDataSource (typeid ); Gv. DataBind (); } } Catch (Exception ex) { SysLog syslog = new SysLog (); Syslog. ListName = ConstData. ListName_PCITC_LS_Schedule; Syslog. LType = "the Item binding event of Repeater is abnormal "; Syslog. WorkFlowName = "lead the calendar management system "; Syslog. Location = "Repeater Binding data: OtherSchedule. aspx "; Syslog. Message = "Page Information loading exception:" + ex. Message; Syslog. DataSource = 0; Logprovider. AddAuditRecordToSource (syslog ); } }
