Remarks
The RecordValidating event is automatically raised when a record is about to be updated, and allows you to specify whether its data is valid. To manually validate the edited record, call the ASPxGridView.DoRowValidation method.
To obtain the edited record’s values, use the event parameter’s ASPxGridDataValidationEventArgs.NewValues property. The old values are returned by the ASPxGridDataValidationEventArgs.OldValues property. If the value is invalid, use the ASPxDataValidationEventArgs.Errors property to specify the error description text. As a result, an error icon will be displayed next to the invalid value. Pointing to the icon shows the hint with the error description.
Use the ASPxVerticalGridDataValidationEventArgs.RecordError property to specify the error text displayed within the record error. This record is automatically displayed below the record if the RecordError property is set to a non- empty string.
