A list below describes the Web Dashboard’s specifics when it operates in the ClientTrustLevel.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 containing in a dashboard xml definition is not passed to the client when you request a dashboard xml file.
