how to make fullscreen toggle button on/off

Question

I'm working on a Win Forms project where I'm trying to create an button to toggle full screen on/off every time i click the button,so if you click once, it becomes full screen, if you click again, it becomes normal again. please tell me how to do that.

Not an exact duplicate but should be useful. Just add a click handler. https://stackoverflow.com/questions/505167/how-do-i-make-a-winforms-app-go-full-screen — Sangram Nandkhile, Mar 02 '20 at 06:23

You can use [`FullScreen`](https://stackoverflow.com/a/32821243/3110834) custom property. — Reza Aghaei, Mar 02 '20 at 07:24

I am not sure about the exact requirements but this should help you.

Add Form1_Load and button1_Click events.

private void Form1_Load(object sender, EventArgs e)
{
    // Normal when the form opens
    WindowState = FormWindowState.Normal;
}

private void button1_Click(object sender, EventArgs e)
{
    // Toggle on a button click
    WindowState = WindowState == FormWindowState.Normal ? FormWindowState.Maximized : FormWindowState.Normal;
}
