public:
static ISet<ElementId^>^ GetAllGlobalParameters(
	Document^ document
)

static member GetAllGlobalParameters : 
        document : Document -> ISet<ElementId>

Parameters

document Document: The document containing the global parameters

Return Value

ISetElementId
A collection of Element Ids of global parameter elements.

Exceptions

Exception	Condition
ArgumentException	Global parameters are not supported in the given document. A possible cause is that it is not a project document, for global parameters are not supported in Revit families.
