Hi experts
I would like some advice on a proper way to display in Winform the following:
They need to be data-bound to an object such that "Infinite" is represented by integer '0', "30" as '30', etc. (ie. 1...29 are prohibited.)

   Infinite
   30
   31
    :
    :
   99999

I guess I have two options: comboBox or domainUpDown.
Is it possible that when user types "I" or "i", then "Infinite" shows up immediately?

Thanks in advance.

What you need and what you display are 2 separate items.  
0 will display 0 unless you override it and tell it to display infinite.. you also need to do the converse if the user enters Infinite then you pass back to the backend a 0.  You also need data validation to ensure the range of 1-29 is excluded.. or returned back to the user as an error.

Used a comboBox and bound it to a Dictionary.
