I have the following Grid. The problem is I can not add a RequiredFieldValidator for the GridDateTimeColumn in edit mode, as I did for the other columns. I would like to know if it is possible, in the code behind C#, to disable the insert button (the tick sign) when the date is not valid or if I can add a validator for the date, that would not allow to insert an item if the corresponding date is not valid. I have also attached a picture.

Thank you very much for any idea, Alexandru Popa.
