Thanks, Depends on what design pattern (if any) you are following.Technically speaking you should remove your business logic away from your UI layer and have some sort of Validation Object to validate the data in your presentation layer and then post back the results to your view.In Visual basic i'm trying to make a field required by preventing the user to leave the active cell if it's empty. The first one is the ID which is automaticly filled in on adding a new row, the second one is the name. On form load there are 4 items loaded into the grid. When this event is canceled in virtual mode, the Cell Value Pushed event will not be raised.
Handle the Cell Validated event to perform post-validation processing.But whenever I moved the focus to another row, Row Leave is called first before Cell Leave/Cell Validating.Is there another way of validating the cell when leaving a row?Canceling this event cancels the changes to the current cell.When this event is canceled in data-bound mode, the new value is not pushed to the underlying data source.Yeah, I agree with that if it is for validation only.
