DataGridView::RowValidating Event

 

Occurs when a row is validating.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
event DataGridViewCellCancelEventHandler^ RowValidating {
	void add(DataGridViewCellCancelEventHandler^ value);
	void remove(DataGridViewCellCancelEventHandler^ value);
}

This event is analogous to the Control::Validating event. Use this event to perform validation on all the values of a row. If the row does not pass validation, set the CancelEventArgs::Cancel property to true. Canceling this event prevents the RowValidated, Control::Validating, and Control::Validated events from occurring, and also prevents the user from leaving the invalid row and prevents the row from being saved to an external data source in data bound mode.

For more information about handling events, see NIB: Consuming Events.

The following code example uses RowValidating to check if valid track and release dates are entered.
