EventFilter SelectClause|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Hello I have a question regarding the EventFilter SelectClauses. I'm using the .Net Stack.

Lets say I have created a new EventType (MyDiscreteAlarmState) that derives from DiscreteAlarmState.

I have added a new double property (doubleAuto) to MyDiscreteAlarmState

How do I have to adjust the default EventFilter that the value "doubleAuto" is send with the event?

EventFilter.AddSelectClause(ObjectTypes.BaseEventType,"doubleAuto") doesnt work.

The nodeId of "doubleAuto" is: "ns=2;i=40"

internal class MyDiscreteAlarmState : DiscreteAlarmState
{
private BaseDataVariableState _AutomaticAdditionalDouble;

public MyDiscreteAlarmState(NodeState parent, ISystemContext systemContext, NodeId nodeId) : base(parent)
{

_AutomaticAdditionalDouble = new BaseDataVariableState(this);
_AutomaticAdditionalDouble.Create(systemContext,
null,
new QualifiedName("doubleAuto", 0),
null, true);
_AutomaticAdditionalDouble.Value = 199;

AddChild(_AutomaticAdditionalDouble);
}
}

Thank you very much
