Hi,
Thank you. I get it.
I have another problem here. I have a grid's column that show numeric value
(e.g. 11.00) It is allowed to be changed by user. Once user click on the column, and key in character "+", the grid's column show "+ 1.00". However, if user pree after key in "+", the value of the column will be "0.00" instead of "1.00".
Is it the behaviour of grid? Any workaround?

Thank you

I am not the worst man in this world either.
I just as same as all of you.
I still need to learn from my mistakes...
