Property Value

The value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

The EventData property contains a OpcLabs.EasyOpc.UA.UAEventData object.

When OpcLabs.BaseLib.OperationModel.OperationEventArgs.Succeeded is false, this property is always a null reference. When OpcLabs.BaseLib.OperationModel.OperationEventArgs.Succeeded is true, this property is a null reference indicating that the monitored item has become operative, or it is a non-null when the server has delivered the event data. Note that this is different from the behavior of AttributeData, which is always non-null when OpcLabs.BaseLib.OperationModel.OperationEventArgs.Succeeded is true.
