#270 – Minimum and Maximum Window Size

By default, there are no upper or lower limits for the size of a window in WPF–you can shrink a window to the point where none of its content is visible and you can maximize a window so that it takes up the entire desktop.

You can use the MinWidth and MinHeight properties to dictate the minimum dimensions for the window.  When resizing the window, you’ll be unable to make the window any smaller.

<Window
	Width="400" Height="300" MinHeight="100" MinWidth="200">

You can use the MaxWidth and MaxHeight properties to dictate the maximum dimensions for the window.  When resizing the window, you’ll be unable to make the window any larger.  If you try maximizing the window, it will be constrained to the maximum size.
