I tried with the normal textbox and it behaved the same way (no surprise). I guess I would have to go through some troubles unbinding it and biniding back (as you showed).

I tried quickly the other two classes I found (by Rick Borup and by Dorin V), but they both do something different. I simply want to be able to click in the textbox and be able to insert the digit which I type into the middle of the number not overwriting the next digit.
