Remarks

Warning

Working mode does not influence server settings. Initially, the server works at the ClientTrustLevel.Full trust level. Verify trust level and specify the actions a client can initiate on the server.

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.

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.
