How to: Disable a Confirmation Dialog in an ASP.NET Core Blazor Application

• Dec 22, 2023

In XAF ASP.NET Core Blazor applications, a confirmation dialog appears if you attempt to exit a view without saving your changes. The following Controllers implement this functionality:

• ConfirmationDetailViewController in Detail Views.
• ConfirmationListViewController in List Views.

This topic demonstrates how to disable the confirmation dialog in a Detail View.

Step-by-Step Instructions

1. In the YourSolutionName.Blazor.Server\Controllers folder, create a new Controller and name it BlazorSuppressConfirmationsController.

2. Replace the auto-generated code with the following code snippet:

3. Build the project and run the application. Open a Detail View and change a property value. When you close the view, XAF does not save the changes and the confirmation dialog does not appear.

Tip

The ConfirmationDetailViewController and ConfirmationListViewController are active for non-persistent objects only if the AutoSetModifiedOnObjectChange property is set to true.
