為了驗證驗證SqlDataSource和GridView刪除行時的事件執(zhí)行循序，寫了以下代碼：
前臺：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="gridView.aspx.cs" Inherits="gridView" %>
<!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>無標題頁</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="a" DataSourceID="SqlDataSource1"
onrowdeleted="GridView1_RowDeleted" onrowdeleting="GridView1_RowDeleting">
<Columns>
<asp:CommandField ShowDeleteButton="True" />
<asp:BoundField DataField="a" HeaderText="a" ReadOnly="True"
SortExpression="a" />
<asp:BoundField DataField="b" HeaderText="b" SortExpression="b" />
<asp:BoundField DataField="c" HeaderText="c" SortExpression="c" />
<asp:BoundField DataField="d" HeaderText="d" SortExpression="d" />
<asp:BoundField DataField="e" HeaderText="e" SortExpression="e" />
</Columns>
</asp:GridView>
<br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ABCConnectionString %>"
DeleteCommand="delete from Table1 where a=@a"
ondeleted="SqlDataSource1_Deleted" ondeleting="SqlDataSource1_Deleting"
SelectCommand="SELECT [a], [b], [c], [d], [e] FROM [Table1]">
</asp:SqlDataSource>
</div>
</form>
</body>
</html>
后臺：
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
public partial class gridView : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void SqlDataSource1_Deleting(object sender, SqlDataSourceCommandEventArgs e)
{
Response.Write("SqlDataSource1_Deleting<br>");
}
protected void SqlDataSource1_Deleted(object sender, SqlDataSourceStatusEventArgs e)
{
Response.Write("SqlDataSource1_Deleted<br>");
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Response.Write("GridView1_RowDeleting<br>");
}
protected void GridView1_RowDeleted(object sender, GridViewDeletedEventArgs e)
{
Response.Write("GridView1_RowDeleted<br>");
}
}
刪除一行后輸出一下字符串：
GridView1_RowDeleting
SqlDataSource1_Deleting
SqlDataSource1_Deleted
GridView1_RowDeleted
明顯的是首先觸發(fā)的是GridView的Deleting事件，然后是SqlDatasource的Deleting和Deleted事件，最后觸發(fā)的是GridView的Deleted事件，可以用類似方法寫代碼驗證其它操作的事件執(zhí)行順序。
