Property Value

Type	Description
ClientTrustLevel	A ClientTrustLevel value that specifies a trust level.

Available values:

Name	Description
Full	A client can initiate any action to execute them on a server side.
Restricted	A client cannot initiate actions that can lead to changing a dashboard stored on a server. This trust level can be used to prevent inadvertent or unauthorized modifications to dashboards.

Remarks

Use the ClientTrustLevel property to verify the trust level used to specify which actions a client can initiate on the server.

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.
