IModelActionWeb.ConfirmUnsavedChanges Property

Specifies whether or not a confirmation dialog is displayed by a browser when there are unsaved changes and a user executes the current Action.

Namespace: DevExpress.ExpressApp.Web.SystemModule

Assembly: DevExpress.ExpressApp.Web.v18.1.dll

Declaration

bool ConfirmUnsavedChanges { get; set; }
Property ConfirmUnsavedChanges As Boolean

Property Value

Type Description
Boolean

true, if a confirmation dialog is enabled; otherwise, false.

The following confirmation is displayed by browser when a user clicks an Action whose ConfirmUnsavedChanges property is true.

Action.ConfirmUnsavedChanges

You can change the ConfirmUnsavedChanges value in the Model Editor.

ConfirmUnsavedChanges_Action

By default, the ConfirmUnsavedChanges option is set to true for the following Actions:

*** Cancel

  • ChangeVariant
  • ChooseTheme
  • DialogCancel
  • DialogClose
  • Edit
  • Logoff
  • NextObject
  • New
  • PreviousObject
  • Refresh**

These are Actions, whose execution may lead to loss of unsaved data. If you have implemented a custom Action, you can set the ConfirmUnsavedChanges property to true to display a warning dialog before your Action is executed and there are unsaved data modifications in the current View.

To disable confirmations globally, use the IModelOptionsWeb.ConfirmUnsavedChanges property of the Options node, instead.
