ASP.NET中使用多个runat=server form

时间：2004/11/7 4:10:00来源：本站整理作者：蓝点我要评论(0)

ASP.NET 在同一个页面不支持多个 runat=server forms，要解决这个问题，可以把每个 form 放在一个单独的 panel 控件中，这样用户就可以简单地通过单选按钮在不同 panel 间切换。

代码如下：

2FormExample.aspx



<%@ Page language="c#" Codebehind="2FormExample.cs" AutoEventWireup="false"

Inherits="_3leaf_app.C2FormExample" %>

    

Lookup by

    
checked=True>

    
groupname=g1>

    

    

    

        First Name :

        

        
ControlToValidate="TextBox1">

        

    

    

        Last Name :

        

        
ControlToValidate="TextBox2">

        

    

    

    

        

    

2FormExample.cs



namespace _3leaf_app

{

    using System;

    using System.Collections;

    using System.ComponentModel;

    using System.Data;

    using System.Drawing;

    using System.Web;

    using System.Web.SessionState;

    using System.Web.UI;

    using System.Web.UI.WebControls;

    using System.Web.UI.HtmlControls;



    ///

    ///    Summary description for C2FormExample.

    ///

    public class C2FormExample : System.Web.UI.Page

    {

  protected System.Web.UI.WebControls.Button Button2;

  protected System.Web.UI.WebControls.RequiredFieldValidator RequiredFieldValidator2;

  protected System.Web.UI.WebControls.TextBox TextBox2;

  protected System.Web.UI.WebControls.Button Button1;

  protected System.Web.UI.WebControls.RequiredFieldValidator RequiredFieldValidator1;

  protected System.Web.UI.WebControls.TextBox TextBox1;

  protected System.Web.UI.WebControls.Label Label1;

  protected System.Web.UI.WebControls.Panel Panel2;

  protected System.Web.UI.WebControls.Panel Panel1;

  protected System.Web.UI.WebControls.RadioButton RadioButton2;

  protected System.Web.UI.WebControls.RadioButton RadioButton1;

    

    public C2FormExample()

    {

        Page.Init += new System.EventHandler(Page_Init);

        }



        protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

            }

        }



        protected void Page_Init(object sender, EventArgs e)

        {

            //

            // CODEGEN: This call is required by the ASP+ Windows Form Designer.

            //

            InitializeComponent();

        }



        ///

        ///    Required method for Designer support - do not modify

        ///    the contents of this method with the code editor.

        ///

        private void InitializeComponent()

  {

   RadioButton1.CheckedChanged += new System.EventHandler (this.RadioButton1_CheckedChanged);

   Button1.Click += new System.EventHandler (this.Button1_Click);

   RadioButton2.CheckedChanged += new System.EventHandler (this.RadioButton2_CheckedChanged);

   Button2.Click += new System.EventHandler (this.Button2_Click);

   this.Load += new System.EventHandler (this.Page_Load);

  }



        public void Button2_Click (object sender, System.EventArgs e)

        {

            Label1.Text = "You want to search on last name";

        }



        public void Button1_Click (object sender, System.EventArgs e)

        {

            Label1.Text = "You want to search on first name";

        }



        public void RadioButton2_CheckedChanged (object sender, System.EventArgs e)

        {

            Panel1.Visible = false;

            Panel2.Visible = true;

        }



        public void RadioButton1_CheckedChanged (object sender, System.EventArgs e)

        {

            Panel1.Visible = true;

            Panel2.Visible = false;

        }

    }

}
