    IModelActionBlazor.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.Blazor.SystemModule

    Assembly: DevExpress.ExpressApp.Blazor.v25.1.dll

    NuGet Package: DevExpress.ExpressApp.Blazor

    Declaration

    [DefaultValue(false)]
    bool ConfirmUnsavedChanges { get; set; }

    Property Value

    Type Default Description
    Boolean false

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

    Remarks

    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.
