numeric up down problem

short description of my program:

I have a listbox with therein orderlines (an orderline exists of order number sparepart, description,prize, quantity) now I'm able to change the quantities with an numericupdown(NUD).

I have 2 problems:

1) When someone uses backspace or delete in the NUD and then klick a different orderline the the NUD should be zero again, but it stays empty.

2) When I click the NUD with the Mouse and then a number eg. 5 then in the NUD stand 05 and this should be 5.

can anybody help me?
