Enables you to specify whether the focused cell’s data is valid, and whether the cell’s editor can be closed.

Namespace: DevExpress.UI.Xaml.Grid

Assembly: DevExpress.UI.Xaml.Grid.v21.2.dll

NuGet Package: DevExpress.Uwp.Controls

Declaration

C#

public event GridCellValidationEventHandler ValidateCell

VB.NET

Public Event ValidateCell As GridCellValidationEventHandler

Event Data

The ValidateCell event's data class is DevExpress.UI.Xaml.Grid.Native.GridCellValidationEventArgs.

Remarks

The ValidateCell event occurs before the focused cell’s modified value is posted to a data source, allowing to manually validate its new value.

The focused cell’s new value is returned by the event’s CellValue property. To indicate that the new value is invalid, set the ValidationEventArgs.IsValid property to false.
