don't let go of focus on a cell in matrix
I have a matrix bounded to a certain user - table. I'd like to know how I could make the matrix to act just like the matrix in A/R invoice. Meaning, when the user is on the first cell, I don't want to let the user to go to another column until he inserts a valid value. (in A/R invoice, I can't go to Quantity, unless I write an ItemID). I've tried: oEdit.Active = true, but it seems that the application is doing many actions and it blocks.
And also, if you could give me some hints on how I should program the events on the matrix so it can act just like the A/R invoice matrix.
Thanks so much,
