Solution 1

private void button1_Click(object sender, EventArgs e)
    for (int i = 0; i < Application.OpenForms.Count; i++)

If you wish to have it maximised for only few types of forms, you can put if condition in that for loop.
These lines will make all openforms in your application maximised :)
Also for panel1,
Add line of code,

Let me know if you need any more help..

I missed to add a code block for that line of code. :(

Solution 2

If you want to maximize the form programmatically, set the WindowState property to maximized.
this.WindowState = FormWindowState.Maximized;

If you want to set the window to full screen you can try like this:
        this.TopMost = true;
        this.FormBorderStyle = FormBorderStyle.None;
        this.WindowState = FormWindowState.Maximized;

Solution 3

You can maximize the form you want from another form like below
Form1 form1=new Form1();
          form1.WindowState = FormWindowState.Maximized;

Hope this helps
