Dim markupLayerRecordId As String
Dim documentContextData As NameValueCollection
 
instance.OnUpdate(markupLayer, documentIdentifier, markupLayerRecordId, documentContextData)

   NameValueCollection documentContextData
)

public: virtual void OnUpdate( 
   ref ImGearARTDocumentXML* markupLayer,
   string* documentIdentifier,
   string* markupLayerRecordId,
   NameValueCollection* documentContextData
)

public:
virtual void OnUpdate( 
   ImGearARTDocumentXML^% markupLayer,
   String^ documentIdentifier,
   String^ markupLayerRecordId,
   NameValueCollection^ documentContextData
