Datagridview cell validating e cancel
I am able to validate my value properly but when I try to change it to something valid I get a Data Error. You should never attempt to change the cell value in the handler for this event, because unless you cancel the event (in which case the user is stuck in edit mode), the cell value is set to the value from the editing control immediately after the event finishes.This, therefore, undoes any action you perform in the handler.

Hi there, I have a question regarding datagridview, I add data to the datagridview in an interface and all the validation for the datagridview cell is in the datagridview cell validating event for the datagridview.
I display the data of the is datagridview in another interface and make the cells read-only. But the thing is when I click on a row that data was added previously and press the Add new row the cell validating event is triggered.
But now it is still triggered if the user clicks into the cell to edit the invalid value.
