1. 前端HTML代码
1 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
2
3 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
4
5 <html xmlns="http://www.w3.org/1999/xhtml">
6 <head runat="server">
7 <title>HTML服务器控件</title>
8 <script type="text/javascript" runat="server">
9 //protected void Page_Load(Object sender, EventArgs e) //如果在当前页面设置Load事件, 那么.cs文件中的load的事件将会被覆盖
10 //{
11 // this.MyText.Value = "hello world!"; //设置input的默认值
12 //}
13 </script>
14 <style type="text/css">
15 #MyText
16 {
17 width:188px;
18 }
19 </style>
20 </head>
21 <body>
22 <form id="form1" runat="server">
23 <input id="MyText" type="text" runat="server" />
24 </form>
25 </body>
26 </html>
2.下面是.cs中的load事件, 如果页面中有Page_load事件, 那么该事件将会被覆盖 (Page_load事件→页面初始化事件)
1 using System;
2 using System.Collections.Generic;
3 using System.Web;
4 using System.Web.UI;
5 using System.Web.UI.WebControls;
6
7 public partial class _Default : System.Web.UI.Page
8 {
9 protected void Page_Load(object sender, EventArgs e)
10 {
11 if (!IsPostBack)
12 {
13 this.MyText.Value = "我是首次加载";
14 }
15 else
16 {
17 this.MyText.Value = "我不是首次加载";
18 }
19 }
20 }
