Disabling Minimize & Maximize On WinForm?

Question

Hello SO and happy Friday,

WinForms have those three boxes in the upper right hand corner that minimize, maximize, and close the form. What I want to be able to do is to remove the minimize and maximize, while keeping the close.

I also what to make the close minimize the form instead of closing it.

How can this be done?

Answer 1

Set MaximizedBox and MinimizedBox form properties to False

Answer 2

The Form has two properties called MinimizeBox and MaximizeBox, set both of them to false.

To stop the form closing, handle the FormClosing event, and set e.Cancel = true; in there and after that, set WindowState = FormWindowState.Minimized;, to minimize the form.

Answer 3

Bind a handler to the FormClosing event, then set e.Cancel = true, and set the form this.WindowState = FormWindowState.Minimized.

If you want to ever actually close the form, make a class-wide boolean _close and, in your handler, set e.Cancel to !_close, so that whenever the user clicks the X on the window, it doesn't close, but you can still close it (without just killing it) with close = true; this.Close();

(And just to make my answer complete) set MaximizeBox and MinimizeBox form properties to False.
