ColumnBase.Validate Event

Enables you to validate the active editor’s value.

Namespace: DevExpress.UI.Xaml.Grid

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

NuGet Package: DevExpress.Uwp.Controls

Declaration

C#

public event GridCellValidationEventHandler Validate

VB.NET

Public Event Validate As GridCellValidationEventHandler

Event Data

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

Remarks

When an end-user modifies the focused cell’s value and tries to save the changes (by pressing the ENTER key or moving focus to another cell), the grid validates a new value. First, this value is validated by the editor itself. Then, the column’s Validate event is raised, allowing you to manually validate the cell’s value. Note this event is not fired when changing cell values in code.
