ASP.NET 入手页面控件及事件触发

       搞了两个晚上搞定。。。太弱了。。。button的事件触发一开始没做出来，后来发现是触发函数是要VS自动生成的才行，自己写的没用。。。

前台的aspx代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ControlsORema.Default" %>

<!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">
    <div style="font-family: Inconsolata; font-size: 14px; font-weight: bold">
    
        Page in Visual Studio<br />
        <asp:Label ID="Label1" runat="server" Text="Type in me:"></asp:Label>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <br />
        <asp:DropDownList ID="DropDownList1" runat="server">
            <asp:ListItem>Item0</asp:ListItem>
            <asp:ListItem>Item1</asp:ListItem>
            <asp:ListItem>Item2</asp:ListItem>
            <asp:ListItem>Item3</asp:ListItem>
            <asp:ListItem>Item4</asp:ListItem>
            <asp:ListItem>Item5</asp:ListItem>
        </asp:DropDownList>
    
        <br />
        <asp:Button ID="Button1" runat="server" Text="Click Me" 
            onclick="Button1_Click" />
    
    </div>
    </form>
</body>
</html>

后台的CS代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace ControlsORema
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Write("Hello. Here's what you typed into the text box: <br/>");
            Response.Write(this.TextBox1.Text);
            Response.Write("<br/>");
            Response.Write("And the selected item is: <br/>");
            Response.Write(this.DropDownList1.SelectedItem.Text);
        }
    }
}
