Hello all,

Is anyone aware of a numeric textbox class that has the following behavior:

1 - allows user to type expression i.e. 32+45 and stores result - in this case 77 to field
2 - user could just type +50 to add 50 to the previous value that was in the field and store new value back to field
3 - works/editable in a grid - grid should be "bound" (i.e. display) all correct values but take on described behavior when field gets focus.

I was hoping to avoid having to code this, so if anyone has or knows of a class, I would appreciate being pointed in that direction.

Thanks!
