There seems to be a non-zero percent chance that this might fire incorrectly in some unforeseen situation.

I’d rather code to do exactly what it says it’s doing.

How to efectively validate data entry inside a Data Grid View. Late Validation: This validation is performed after the user is done entering data.

Well, after doing some research and a bit of trial and error, found out a couple of approaches. For the specific project i was working in, it was the perfect choice.

After looking into the problem at some length, MSDN actually seems to offer the best solution right on their Cell Content Click event page. I like that it tells us very specifically what has happened to the grid at the point in time when the event is raised and handled.

It’s important to note that this event will get called twice, once on changing the state of the cell to dirty (before committing changes) and once when changing the cell state back to ‘clean’ (after the changes have been committed).On the other hand, if the user is required to enter data in all the rows and the validation is simple; the first approach is convenient.In order to implement Immediate validation, the event Cell Validation must be handled Ex The validation to check if the cell is in edit mode is very important. For the Late Validation, there must be an event that is perform once the user finish entering data.Its not permissible to have the two selected to true, but they can both be false.
