title: why width property doesn't change from code - WPF
body: <p>I have a grid in WPF application which contains 2 grids.
  The inner grids are width binding - one depend on the other.
  I change the width of one grid from code with a story board and it works.
  but when I try to change it in another method, it does nothing.
  what can cause this behavior? </p>
