System.Windows.Forms.DataGridView.RowValidating Event

Occurs when a row is validating.

Syntax

public event DataGridViewCellCancelEventHandler RowValidating

Remarks

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 System.ComponentModel.CancelEventArgs.Cancel property to true. Canceling this event prevents the DataGridView.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.
