GridView自带编辑删除更新逻辑很简单:操作完,重新绑定。总结总结,防止忘记。。。
效果图:
前台代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="gridView_bianjidelete.aspx.cs" InherITs="gridView_bianjidelete" %> <!DOCTYPE htML> <html XMlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-type" content="text/html; charset=utf-8"/> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCancelingedit="GridView1_RowCancelingEdit"> <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" /> <Columns> <asp:BounDField DataField="ID" HeaderText="产品ID" ReadOnly="True" /> <asp:BoundField DataField="name" HeaderText="产品name" /> <asp:BoundField DataField="stock" HeaderText="库存" /> <asp:CommandField HeaderText="选择" ShowSelectButton="True" /> <asp:CommandField HeaderText="编辑" ShowEditButton="True" /> <asp:CommandField HeaderText="删除" ShowDeleteButton="True" /> </Columns> <RowStyle ForeColor="#000066" /> <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="red" /> <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" /> <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> </asp:GridView> </div> </form> </body> </html>
后台代码:
