You can do one of the following to prevent inadvertent or unauthorized dashboard modifications and protect dashboards stored on a server:

• Handle the DashboardConfigurator.VerifyClientTrustLevel event and set e.ClientTrustLevel to Restricted mode.
• Derive a custom dashboard controller from RestrictedDashboardController instead of DashboardController.

The example shows how to create a restricted dashboard controller for the Web Dashboard in an ASP.NET Core application.

Inherit the RestrictedDashboardController class to create a custom dashboard controller. Add its name (without a Controller prefix) to the following places:

• The RouteBuilderExtension.MapDashboardRoute method when you configure routing;
• The DashboardBuilder.ControllerName method when you configure a control on the page.

In this example, the custom controller name is DefaultDashboard.

• Startup.cs
• DefaultDashboardController.cs
• Index.cshtml
