[ASP.NET]GridView自定义编辑，更新，取消，删除

 1，问题描述

今天在网上看见有人问怎么样自定义GridView的编辑，更新，取消，删除按钮，GridView自带的太难看

2，达到要求

变换编辑，更新，取消，删除按钮


 



3，实现方法

 (1)第一步，将GridView的“CommandField”变为“TemplateFiled模板”

 (2)第二步，将在“编辑模板”里编辑此字段，方法和编辑其他模板一样，比如我的例子是在“ItemTemplate”加入两个ImageButton，在“EditTemplate”中加入两个LinkButton

分别代表编辑，删除，更新，取消

 (3)第三步，就是添加 RowCancelingEdit，RowEditing，RowUpdating，RowDeleting 这些事件，相信大家都会的。

注意：在第二步中的四个控件，需要加上 CommandName，分别为“Edit”，“Delete”，“Update”，“Cancel”。

Ok大功告成！

我的代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="将编辑换成按钮.aspx.cs" Inherits="NOP.GridView总汇.将编辑换成按钮" %>
