    RestrictedDashboardController

VB.NET

Public MustInherit Class DashboardController
    Inherits RestrictedDashboardController

Remarks

A list below describes the Web Dashboard’s specifics when it operates in the Restricted mode:

• Only dashboards stored in dashboard storage can be processed on the client. The 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.

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.
