TextBox Problem with numeric input

Hi!

I have in a WPF Maske 4 TextBoxes...

1. A Number in a length from 9.
--> OK, I can find out is there a number or not and how many character are in the TextBox
     This is finish...

2. A Number with the folowing Input/Output:
    "10.200.333,95-" (Only Numbers and ".,-" allowed...)
                                But only 1 time ".,-"  and i Need an automatic "." for the number
                                eg.: "10000,00" = "10.000,00"

3. A Special Numberfield:
   "10/100/3303"  this is a partnumber from a car....
                          Only Numbers and "/"  are allowed and I Need here to an automatic for this:
                          eg.: "101003303" = "10/100/3303"

4. A TextBox with Auto Number like this:
    "     99,00"  the Field is normal "9999999,99"  so what I mean is an automatic Zero = Space
                      mechanism

Best regards
