You can do one of the following to prevent inadvertent or unauthorized dashboard modifications and protect dashboards stored on a server:
- Handle the
VerifyClientTrustLevelevent and set e.ClientTrustLevel to Restricted mode. - Derive a custom dashboard controller from
RestrictedDashboardController(ASP.NET MVC / ASP.NET Core) instead ofDashboardController.
Restricted mode affects the Web Dashboard in the following manner:
Only dashboards stored in dashboard storage can be processed on the client. Designer mode does not work.
Calling the IEditableDashboardStorage.AddDashboard and IDashboardStorage.SaveDashboard methods leads to an exception.
Information about data sources contained in a dashboard xml definition is not passed to the client when you request a dashboard XML file.
