Disabling Minimize & Maximize On WinForm?

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?

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.

Set MaximizeBox and MinimizeBox form properties to False

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.

Right Click the form you want to hide them on, choose Controls -> Properties.

In Properties, set

• Control Box -> False
• Minimize Box -> False
• Maximize Box -> False

You'll do this in the designer.

How to make form minimize when closing was already answered, but how to remove the minimize and maximize buttons wasn't.
FormBorderStyle: FixedDialog
MinimizeBox: false
MaximizeBox: false

you can simply disable maximize inside form constructor.

 public Form1(){
     InitializeComponent();
     MaximizeBox = false;
 }

to minimize when closing.

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
    e.Cancel = true;
    WindowState = FormWindowState.Minimized;
}

public Form1()
{
InitializeComponent();
//this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
this.MaximizeBox = false;
this.MinimizeBox = false;
}
