I did this around my window in it's Template:

<Border BorderBrush="Transparent" BorderThickness="5" Margin="-5"
        Effect="{DynamicResource ShadowEffect}">
  <...>
</Border>

Negative margin negates border thickness.

In the SizeChanged event you can detect if the window is docked with:

bool isDocked = 
     window.WindowState == WindowState.Normal &&
     window.Width != window.RestoreBounds.Width &&
     window.Height != window.RestoreBounds.Height

at least, this is a pretty good indicator.

There isn't any special event because 'docking' to left/right is not a special operation like minimize/maximize, merely a particular way of repositioning of the window. The user can mimic 'docking' exactly by restoring, moving and resizing the window. Therefore, your UI logic appears questionable. Imagine the user restoring the window and then resizing it so that it fills approximately half a screen close to the right edge of the screen. What should happen?

Protip: there may be multiple monitors and your window may straddle them.
