.aspx代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TextBox_test.aspx.cs" Inherits="TextBox_test" %>
<!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">

</head>
<body>
<form id="form1" runat="server">
这是一个HTML input控件：<input id="Text1" type="text" /><br />
这是一个ASP标准服务器控件：<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
这是一个带有RUNAT属性的HTML控件：<input id="Text2" type="text" runat="server" /><br />
<asp:Button ID="Button1" runat="server" Text="更改第一个文本框的值（后台程序无法做到）"
/>
<br />
<asp:Button ID="Button2" runat="server" Text="更改第二个文本框的值"
onclick="Button2_Click" />
<br />
<asp:Button ID="Button3" runat="server" Text="更改第三个文本框的值"
onclick="Button3_Click" />
</form>
</body>
</html>
.aspx.cs代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class TextBox_test : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { } protected void Button2_Click(object sender, EventArgs e) { TextBox1.Text = DateTime.Now.ToLongDateString(); } protected void Button3_Click(object sender, EventArgs e) { Text2.Value = http://www.mamicode.com/DateTime.Now.ToString();>

<h3>文本框的多种表现形式</h3>
<div class="d1">单行文本框：
<asp:TextBox ID="txt_s" runat="server" Enabled="false" ></asp:TextBox>
<asp:Button ID="btn_reads" runat="server" Text="读取内容并显示"
onclick="btn_reads_Click" />
</div>
<div class="d1">多行文本框：
<asp:TextBox ID="txt_m" runat="server" TextMode="MultiLine"
Height="200px" Width="200px" ></asp:TextBox>
<asp:Button ID="btn_readm" runat="server" Text="读取内容并显示"
onclick="btn_readm_Click" />
</div>
<div class="d1">密码文本框：
<asp:TextBox ID="txt_p" runat="server" TextMode="Password" ></asp:TextBox>
<asp:Button ID="btn_readp" runat="server" Text="读取内容并显示"
onclick="btn_readp_Click" />
</div>
<div class="d1">HTML文本框：
<input id="txt_html" type="text" runat="server" />
<asp:Button ID="btn_readhtml" runat="server" Text="读取内容并显示"
onclick="btn_readhtml_Click" />
</div>
<br /> <br /> <br />
显示结果的层：
<div id="div_result" runat="server" > </div>
</div>
</form>
</body>
</html>
.aspx.cs代码如下：

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Sample_3_1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btn_reads_Click(object sender, EventArgs e)
{
//div的InnerText属性调用；请注意很多其他的HTML控件都有InnerText属性，如<p>,<span>,<td>...
div_result.InnerText = txt_s.Text;
}
protected void btn_readhtml_Click(object sender, EventArgs e)
{
div_result.InnerText = txt_html.Value;
}
protected void btn_readm_Click(object sender, EventArgs e)
{
div_result.InnerText = txt_m.Text;
}
protected void btn_readp_Click(object sender, EventArgs e)
{
div_result.InnerText = txt_p.Text;
