Code below. Maybe this is what you need.

private void btnExit_Click(object sender, EventArgs e)
        {
            this.Visible = false;
        }

Do you need interact with both windows? If only Form2 gets the attention, you can solve it with the mentioned ShowDialog (). Otherwise you can check with OnClosing if Form2 still open and refuse it. Here you have a nice code snip to disable the close button: http://social.msdn.microsoft.com/Forums/windows/en-US/32148556-2640-4d79-a7b6-f13f9ce3420a/how-to-enabledisable-the-close-buttonx-in-window-form-?forum=winforms

You can simply open Form2 using Form2.ShowDialog(): it this is called from Form1 code then Form2 is modal with respect to Form1 (that is you can interact no more with Form1 until you close Form2) and so the user is forced to close Form2 before being able to close Form1.

Please mark this answer as accepted if it responds your question.

Use the Form.ShowDialog() method instead of Show() when you display the child form.
