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);

        }
