I tried to understand how to control the editing of the grid and how to use the Masked creating a small program.
Everything seems to work, I have just a minor inconvenience, when validation fails the cell text does not display the value entered and checked but the previous year.
Is there any option to avoid this?
I enclose the sample program where you can see how the grid show the old value if you put the wrong data in the column "Line"
Can anyone give me a hint?
