ModificationsController.ModificationsCheckingMode Property

Applicable to List Views. Specifies when the modifications made in an editable List View are committed.

Namespace: DevExpress.ExpressApp.SystemModule

Assembly: DevExpress.ExpressApp.v24.1.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

[DefaultValue(ModificationsCheckingMode.Always)]
public ModificationsCheckingMode ModificationsCheckingMode { get; set; }

VB.NET

<DefaultValue(ModificationsCheckingMode.Always)>
Public Property ModificationsCheckingMode As ModificationsCheckingMode

Property Value

Type	Default	Description
ModificationsCheckingMode	Always	A ModificationsCheckingMode enumeration value that specifies when the modifications made in an editable List View are committed.

Available values:

Name	Description
Always	Changes are committed when a user proceeds to the next record and when the List View is closed. Do not enable this mode when the new item row (see IModelListViewNewItemRow.NewItemRowPosition) is visible in the GridListEditor .
OnCloseOnly	Changes are committed when the List View is closed.

Remarks

This property is set to Always in all XAF projects.

In WinForms applications, the value is overridden and set to OnCloseOnly for List Views. This means, data modifications are committed when a List View is closed. Set the ModificationsCheckingMode property to ModificationsCheckingMode.Always to commit modifications each time a record is modified. Changes will be committed and confirmation will be displayed when a user proceeds to the next record in the editable List View.
