Something easy I'm missing here ...

I have a numeric column in a grid. I'd like the values to display using a value for inputmask of '9,999,999'.

However, the user can modify the data in this column, and the inputmask really screws things up when the user tries using the keyboard.

So, I'll looking for the way to set the inputmask so that it applies for each row, unless the user is editing the value, in which case I want to discard the inputmask. Somehow, this seems related to "sparse" (which is .F. is my example)?

Thanks
