title: WPF - Resizing Children to Fill a Parent
body: <p>In WPF, I simply want to have a 'container' which has 3 textblocks.  I would like these 3 textblocks to be sized so they each take up 1/3 of the parent's width.  I noticed that the stackpanel sizes the last child automatically, but is there a way to size each child automatically?</p>
