Hi all,
I use vb.net , datagirdview(DataGridViewTextBoxColumn). i have a Date format field(DataGridViewCellStyle { Format=d }). (dd/MM/yyyy)

But i don't know how to CellValidating is better.Anyone try to do this ?
I want to + "/" "/" to cell.value when user entry 2 char (Day value), 2 char (Month value) and 4 char(year value), but i can't control user must entry numberic in cell,becuase i havn't find cell keypress event.

After when user entered cell.value and check valid Date.
for example 15/11/2012

Anyone know how to do? Thank you
