其實也沒什麼困難,比較棘手的是table的屬性、樣式調整
執行結果:
先看ListView的實現方式:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="ListViewHeaderFooter.aspx.vb" Inherits="ListViewHeaderFooter" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <%--GridView的數據來源--%> <asp:SqlDataSource runat="server" ID="sds_test" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [CategoryID], [CategoryName], [Description] FROM [Categories]" /> <table border="1" cellspacing="0"> <tr> <th style="width:80px" > CategoryID </th> <th style="width:105px" > CategoryName </th> <th > Description </th> </tr> <tr> <td colspan="3"> <asp:Panel ID="tablePanel" runat="server" Height="100px" ScrollBars="Auto"> <asp:ListView ID="lv_Data" runat="server" DataSourceID="sds_test"> <ItemTemplate><%--Repeat的地方--%> <tr> <td style="width:80px"> <asp:Label runat="server" Text='<%# Eval("CategoryID") %>' /> </td> <td style="width:105px"> <asp:Label runat="server" Text='<%# Eval("CategoryName") %>' /> </td> <td> <asp:Label runat="server" Text='<%# Eval("Description") %>' /> </td> </tr> </ItemTemplate> <LayoutTemplate> <table id="itemPlaceholderContainer" runat="server" border="1" cellspacing="0"><%--table的屬性要和最外層的一樣,所有table的外觀才會一致--%> <tr id="itemPlaceholder" runat="server"> </tr> </table> </LayoutTemplate> </asp:ListView> </asp:Panel> </td> </tr> <tr> <td colspan="3" align="center"> Footer Hello!! </td> </tr> </table> </form> </body> </html>
↑ListView這樣就完了(建議使用ListView實現這樣的功能)
GridView的實現方式(前台代碼):
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default6.aspx.cs" Inherits="Default6" Debug="true" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <%--GridView的數據來源--%> <asp:SqlDataSource runat="server" ID="sds_test" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [CategoryID], [CategoryName], [Description] FROM [Categories]" /> <%-- cellspacing="0" border="1" style="border-collapse:collapse;" 為GridView呈現<table>的預設屬性,因為Code-Behind目前找不到抓取方法,所以寫死--%> <table cellspacing="0" border="1" style="border-collapse:collapse;" > <%--GridView Header的Html Code--%> <asp:Literal id="li_header" runat="server" /> <tr> <td id="td_showGridView" runat="server" > <asp:Panel ID="tablePanel" runat="server" Height="100px" ScrollBars="Auto"> <asp:GridView runat="server" ID="gv_Data" AutoGenerateColumns="False" ShowFooter="True" DataKeyNames="CategoryID" DataSourceID="sds_test" onrowdatabound="gv_Data_RowDataBound" ondatabound="gv_Data_DataBound" > <Columns> <asp:BoundField DataField="CategoryID" HeaderText="CategoryID" SortExpression="CategoryID" ItemStyle-Width="80px" /> <asp:BoundField DataField="CategoryName" HeaderText="CategoryName" SortExpression="CategoryName" ItemStyle-Width="105px" /> <asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" /> </Columns> </asp:GridView> </asp:Panel> </td> </tr> <%--GridView Footer的Html Code--%> <asp:Literal id="li_footer" runat="server" /> </table> </form> </body> </html>
protected void gv_Data_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType==DataControlRowType.Header) { StringWriter sw=new StringWriter(); HtmlTextWriter writer=new HtmlTextWriter(sw); e.Row.Cells[0].Width = 80; e.Row.Cells[1].Width = 105; e.Row.RenderControl(writer); e.Row.Visible = false; li_header.Text = sw.ToString(); } if (e.Row.RowType == DataControlRowType.Footer) { e.Row.Cells[0].ColumnSpan = gv_Data.Columns.Count; e.Row.Cells[0].HorizontalAlign = HorizontalAlign.Center; e.Row.Cells[0].Text = "Footer Hello!"; e.Row.Cells[1].Visible = false; e.Row.Cells[2].Visible = false; StringWriter sw = new StringWriter(); HtmlTextWriter writer = new HtmlTextWriter(sw); e.Row.RenderControl(writer); e.Row.Visible = false; li_footer.Text = sw.ToString(); } } protected void gv_Data_DataBound(object sender, EventArgs e) { td_showGridView.Attributes["colspan"] = gv_Data.Columns.Count.ToString(); }
