Syntax

C#

Visual Basic
`Public Shared Function AreGlobalParametersAllowed ( _ document As Document _ ) As Boolean`

Visual C++
`public: static bool AreGlobalParametersAllowed( Document^ document )`

Parameters

document: Type: Autodesk.Revit.DBDocument

First of all, global parameters can be had in main project documents only; they are not supported in family documents. However, there may also be other circumstances due to which global parameters may be disallowed in a particular project, either temporarily or permanently.

public bool ContainsGlobalParameters(Document document)
{
    // Global parameters are not available in all documents.
    // They are available in projects, but not in families.
    if (GlobalParametersManager.AreGlobalParametersAllowed(document))
    {
        return (GlobalParametersManager.GetAllGlobalParameters(document).Count > 0);
    }

    return false;
