So the validation logic you apply in a handler for the Cell Validating event should validate against the display patterns for the cell, which don't necessarily map directly to the storage patterns for the corresponding data member in the data source.These events follow the same pattern as the control validating events, letting you cancel validation by setting their event argument Cancel property to true.In the case of the Row Validating event, the event argument type is Data Grid View Cell Cancel Event Args; for Cell Validating, the event argument type is Data Grid View Cell Validating Event Args.When this event is canceled in virtual mode, the Cell Value Pushed event is not raised.The Cell Validating event only fires when losing input focus (before leaving the current cell) or when Gc Multi Row validates.
