which events does BringToFront() method trigger?

问题

I have two Forms, Form1 and Form2 and I want to do something in Form2 whenever I call Form2.BringToFront() in Form1.

class Form1 : Form
{
    button1_MouseClick()
    {
        Form2.BringToFront();
        // trigger an event an do something in Form2 
    }
}

class Form2 : Form
{
    UnknownEvent_EventHandler()
    {
        //do something
    }
}

But Documentation on BringToFrontMethod doesn't say which events does this method trigger.

Notice I don't want to create a public method on Form2 and call it.

Well it doesn't fire one directly that I know of, but as a result of its Activation(focus) being changed the Form.Activated Event will fire. You can find the code documentation here. Here is a little sample code:

private void Form1_Activated(object sender, System.EventArgs e)
{
   //What do you want to happen?
}

If this helps you be sure to mark it as the answer.

 Form2 form2 = new Form2();
        private void button1_Click(object sender, EventArgs e)
        {
            form2.Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Application.OpenForms["Form2"].BringToFront();
        }
