Remove padding from TextBox in WPF

If you add the attribute

Padding="0, 0, 0, 0"

to most WPF elements e.g. <Label></Label>, the text is placed in the top left hand corner with no space between the left and top sides.  However if you try it with a TextBox element it appears to have no effect.

Fortunately as a workaround you can set the padding to have negative values.  So e.g. if I want a standard TextBox element, with standard fontsize, with no space above the text, doing something like:

Padding="0, -2, 0, 0"

Will have the desired effect.
