GridControl.ValidateRow Event

Enables you to specify whether the focused row's data is valid, and whether the row can lose focus.

Namespace:DevExpress.UI.Xaml.Grid
Assembly:DevExpress.UI.Xaml.Grid.v18.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type GridRowValidationEventArgs containing data related to this event.

The following GridRowValidationEventArgs properties provide information specific to this event.
Property Description
ErrorContent Gets or sets an object that describes the validation error.
ErrorType Gets or sets the error type.
Handled
IsValid Gets or sets a value specifying whether the value is valid.
Row Gets the processed row.
RowHandle Gets the processed row's handle.
UpdateSource Gets the action that caused the validation.
Value Gets the editor's value.

Expanded Remarks

Row validation is performed within the ValidateRow event handler. This event is automatically fired after the focused row's data has been modified and it is about to lose focus. To manually force row validation, call the DataControlBase.CommitEditing method.

The processed row is returned by the event parameter's GridRowValidationEventArgs.Row property. Its handle is returned by the GridRowValidationEventArgs.RowHandle. After cell values have been obtained, you can verify whether these values meet your validity criteria. If the row fails validation, set the event's IsValid parameter to false. Otherwise, leave the IsValid parameter set to true.

To learn more, see Row Validation.
