If one of the form is maximized, then it means it will occupy the whole screen.
Then how could the second form be visible?

I can see a instance of second form, when opened in maximized mode.

What you are describing is the expected behavior.

What phil.o and Wes Aday stated is true - the behavior you witness is expected.

However, if you limit the size of each form, then you can control how much of the desktop landscape the forms will occupy when they are maximized. One way you achieve this is by overriding the OnSizeChanged event handler. The following application demonstrates this solution.

C#

using System;
using System.Windows.Forms;

namespace MaximizeWindowOverride
    {

    public partial class Form1 : Form
        {

        // ******************************************* class constants

        const int       MAXIMUM_HEIGHT = 500;
        const int       MAXIMUM_WIDTH = 600;

        // ******************************************* class variables

        FormWindowState current_window_state;

        // ***************************************************** Form1

        public Form1 ( )
            {

            InitializeComponent ( );

            current_window_state = this.WindowState;
            }

        // ********************************************* OnSizeChanged
        
        protected override void OnSizeChanged ( EventArgs e )
            {

            base.OnSizeChanged ( e );

            if ( ( this.WindowState == FormWindowState.Maximized ) &&
                 ( current_window_state != FormWindowState.Maximized ) )
                {
                this.Width = MAXIMUM_WIDTH;
                this.Height = MAXIMUM_HEIGHT;

                this.WindowState = FormWindowState.Normal;
                }

            current_window_state = this.WindowState;
            }

        } // class Form1

    } // namespace MaximizeWindowOverride

Hope that helps.
