TextBox: insert spaces for credit card number?

Question

I have a credit card number text box which i want it to automatically insert spaces every 4 digits as the user types in the credit card number. how can i achieve that(in an elegant way if there is)? i am thinking if regular expressions can achieve it?

You don't need regular expressions to for a simple count. Handle the KeyDown event and validate each key stroke. Insert a space if needed. — paparazzo, Aug 13 '13 at 16:19
If the numbers are separated if the norm not to have 4 separate text boxes with 4 digits in each? — Fraser, Aug 13 '13 at 16:20

Try using a MaskedTextBox from the WPF Toolkit.

<wpfx:MaskedTextBox Mask="0000 0000 0000 0000" />
