If you are using DataBinding for the TextBox content, it can be simply achieved by specifying StringFormat to your binding, for instance:

<TextBox Text="{Binding YourProperty, StringFormat=\{0:F2\}}"/>

See number formatting documentation at MSDN.

If you're not using DataBinding, I'm sure someone else will provide an answer for you.
