Summary
Occurs just before an N-SET-REQ is sent to the SCP.
Syntax
C#
C++/CLI
public event EventHandler<CommonEventArgs> BeforeNSet 
public: 
event EventHandler<CommonEventArgs^>^ BeforeNSet 
Event Data

The event handler receives an argument of type CommonEventArgs containing data related to this event. The following CommonEventArgs properties provide information specific to this event.

PropertyDescription
AffectedClass Gets the affected class.
DataSet Gets the data set.
Instance Gets the instance.
MessageID Gets or sets the message ID.
PresentationID Gets the presentation context id.
Scp (Inherited from Leadtools.Dicom.Scu.Common.BaseEventArgs)Gets the SCP.
