asp.net--TextBox属性全研究

.aspx代码例如以下：

<%@ 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">

<title></title>

</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代码例如以下：

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 = DateTime.Now.ToString();

    }

}

.aspx代码例如以下：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Sample 3-02.aspx.cs" Inherits="Sample_3_1" %>

<!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">

<link href="StyleSheet.css" rel="stylesheet" type="text/css" />

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<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">password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代码例如以下：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class 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；请注意非常多其它的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;

    }

}
