窗体2 和窗体3 都是动态创建出来的

现在 FORM3.TEXT要即时 = FORM2.TEXT

FORM1窗体代码

Form2 f2 = new Form2();
Form3 f3 = new Form3();
private void Form1_Load(object sender, EventArgs e)
{
f2.XYZ += new Form2.CallBack(GetForm2TextBox1Text); f2.Dock = DockStyle.Fill;
f2.TopLevel = false;
f2.FormBorderStyle = FormBorderStyle.FixedToolWindow;
f2.Parent = panel1;
f2.Show(); f3.Dock = DockStyle.Fill;
f3.TopLevel = false;
f3.FormBorderStyle = FormBorderStyle.FixedToolWindow;
panel2.Controls.Add(f3);
f3.Show();
} private void GetForm2TextBox1Text(string s)
{
f3.textBox1.Text = s;
}

FORM2窗体代码

public delegate void CallBack(string s);
public event CallBack XYZ; private void textBox1_TextChanged(object sender, EventArgs e)
{
XYZ(textBox1.Text);
}

FORM3窗体代码

无

FORM1窗体代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
} Form2 f2 = new Form2();
Form3 f3 = new Form3();
private void Form1_Load(object sender, EventArgs e)
{
f2.XYZ += new Form2.CallBack(GetForm2TextBox1Text); f2.Dock = DockStyle.Fill;
f2.TopLevel = false;
f2.FormBorderStyle = FormBorderStyle.FixedToolWindow;
f2.Parent = panel1;
f2.Show(); f3.Dock = DockStyle.Fill;
f3.TopLevel = false;
f3.FormBorderStyle = FormBorderStyle.FixedToolWindow;
panel2.Controls.Add(f3);
f3.Show();
} private void GetForm2TextBox1Text(string s)
{
f3.textBox1.Text = s;
}
}
}
