How do I remove the maximize button from a form? I've already disabled it but it still shows up, it just doesn't work. I want a form with only the close and minimize buttons. It's a Windows Form Application and I'm using Visual Studio 2010.
Hiding the maximize button is not possible without you painting your own window frame.
Having it disabled tells the user that he can't maximize the form which is good UX. Hiding it doesn't help because double clicking the title bar will still maximize the window (if you haven't disabled Maximize).
You can set See update below.
FormBorderStyle set to the
SizableToolWindow, but then the form will not be displayed in the Windows task bar or in the ALT+TAB window.
You can hide the entire
ControlBox which will also remove
Close as well as the context menu.
Pick your poison!
I decided to revisit the landscape with various options and it seems that:
FixedToolWindow/SizableToolWindowno longer hides the app in task bar or ALT+TAB window in Windows 7 and up.
ShowInTaskbarexclusively decides Show/Hide effect in this case (thanks to @pinowthebird for nudging me to take a re-look).
FixedDialogalso hides the maximize/minimize buttons and shows up in task bar, although the default icon is now lost (not sure why).
MaximizeBox = Falsedoes NOT hide the buttons, again contrary to the documentation. It simply disables it (and maximize functionality via toolbar double click).
MaximizeBox = Falseand
MinimizeBox = Falsehides them, irrespective of

Based on your requirements, you can either opt for 1, 2 or 3. Hope this helps future visitors.
Disclaimer: These tests were done in VS 2015, .Net 4.6 and a brand new WinForm app. The documentation says that these properties were available since .Net 1.1. However, as you can see in the screenshots - take the documentation with a grain of salt! Also the OS plays a vital role in the outcome.
