Declaration
Remarks
Warning
The working mode does not influence the server settings. Initially, the server works at the ClientTrustLevel.Full trust level. Verify the trust level and specify which 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.
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.
