Hi, my grid have a cell with editor control assigned to numeric editor control (type double nnnn,nn) on "quantity" cell. I written code for this behaviour: When user the edit the quantity cell, and press key down or key up, the edit goes on same cell of previous or next row, and the value of cell is confirmed. This work but there are a little problem: the numeric value in ultra numeric control when recieve key up or down is changet of one unit. For example: 15,00 then I press key up the edit go correctly on previous row but 15,00 is now 15,01. I think this is a behaviour of ultra numeric control with keys up and bown, but in this case I would to disable this feature. There is a way to do this ? Thanks, and sorry for bad english. Andrea.
