title: how to set inner text margin of button
body: <p>I have a WPF button with some text in it. If I don't set button's width manually, then the button width will be almost of text's width, and it doesn't look very good. I don't want to calculate the width of each button. Is there a more convenient way to specify the relative width of the button? For example in CSS you can specify padding or margin. Is there something like that in WPF?</p>
