public bool IsNotLoadedIntoMultipleOpenDocuments()

Public Function IsNotLoadedIntoMultipleOpenDocuments As Boolean

public:
bool IsNotLoadedIntoMultipleOpenDocuments()

Return Value

Revit can open several documents which contain the same link. If this is the case, Revit cannot reload the link, as doing so would make changes to a non-active document. You will need to close one or more documents in order to modify the link.

If the link is loaded into multiple documents across multiple sessions of Revit, this function will return true. We only check the current session of Revit. It is safe to reload a link which is loaded into multiple sessions, as long as it is not loaded into more than one document in any one session.

If this function returns true, it is safe to reload the link.
