Datagridview cell validating cancel
The cell is then waiting for a correct value and won't let the user to simply cancel&revert his action...
Here is what the validation method looks like : to get what you want.
So I jump into my Cancel button's code and try to bypass validation.
I play with , etc to no avail, and after a quick trace I see why none of it worked - the validation handler is making my code unreachable.
Unfortunately, this seems to fail if the user has entered invalid data or simply partially entered a row in any way that fails validation.
Cancel only works if all form data is valid, which is obviously problematic.
Convert your comment to an answer and I will upvote you.
I would like to manipulate a cell in my Data Grid View when it is validating so that if the user enters a value that is not valid for the database, but is easily converted to valid data, the program will change the value to an appropriate one.
Data Grid View Cell Event Args) _ Handles data Grid View1. Using Windows Authentication (also known as integrated security) is a more secure way to control access to a database.

This Data Grid View exists as part of an entry form with a Cancel button.
In the event that the Cancel button is clicked, I would like to cancel any pending edits to the DGV, reject all changes to its underlying Data Table, etc.
