C# TabContral选项卡中加载显示窗体后 实现单向参数传递测试代码示例(图)

public partial class Form1 : Form

   {

       private TabPage tbMobile = null; 

       private TabPage tbUnion = null;

       Form2 form2 = null;        //先在这里声明，便于加载后引用

       public Form1()

       {

           InitializeComponent();

       }

       private void button1_Click(object sender, EventArgs e)

       {

           form2.textBox2.Text = textBox1.Text;            //这里就可以引用了，form2的textBox2必须先设置成public

       }

       private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)

       {

           form2.textBox2.Text = textBox1.Text;            //切换选项卡时也获取最新的输入参数

       }

       private void generatefm_Click(object sender, EventArgs e)

       {

           tbMobile = new TabPage("中国");

           tbMobile.Name = "tbmobile";

           tabControl1.Controls.Add(tbMobile);

           form2 = new Form2(textBox1);

           // Form2 form = new Form2(); 

           form2.TopLevel = false;

           form2.BackColor = Color.White;

           form2.Anchor = AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right;

           form2.FormBorderStyle = FormBorderStyle.None;

           form2.Show();

           tbMobile.Controls.Add(form2);

           tabControl1.SelectedIndex = 2;

       }

   }
