I don't even remember how many times it bit me, and after a while I even gave up trying to understand what it actually meant. It became one of the things to try before getting the grid to work as desired.

If you are right, then I'm still confused because... In this case, I have Column.Sparse=.T. but yet the Column.DynamicInputMask="@R ###,###,###.##" setting *IS* applying to all rows.

It has always be my understanding that only the "DynamicCurrentControl" and "CurrentControl" behavior was affected by Sparse property, but not the the other Dynamic* properties, as you stated. At least, that is the result I am getting here. And, in this case, the only control in the column is the standard textbox that is included in each column, so you would think the whole issue of Sparse should be moot, since there are not two controls from which to choose.

The Help mentions Sparse in DynamicCurrentControl and CurrentControl, but it is not mentioned in DynamicInputMask.

Anyway, I've always thought about it like this: "sparse" means 'not too much', or 'not very often', so, that jives with only using the specified CurrentControl on the current row when Sparse=.T., and the regular textbox on all the other rows. But again, only with respect to CurrentControl, not all the the Dynamic* properties.
