前台页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
<!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>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<asp:Panel runat="server" ID="p1"></asp:Panel>
</form>
</body>
</html>
后台页面

public partial class Default3 : System.Web.UI.Page
{
PlaceHolder myholder;
TextBox myt ;
protected void Page_Load(object sender, EventArgs e)
{
creatwebcontrol();
}
private void creatwebcontrol()
{
myholder = new PlaceHolder();
myt = new TextBox();
//myt.Height = 20;
//myt.Width = 200;
Button mybutton = new Button();
mybutton.Text = "获取内容";
mybutton.Click+=new EventHandler(mybutton_Click);
this.p1.Controls.Add(myt);
this.p1.Controls.Add(mybutton);
}
public void mybutton_Click(object sender, EventArgs e)
{
Response.Write(myt.Text);
}
}
