Hi all,
So far I see all .NET event can only support an Event signature without specifying any filter from the client side ( for example MachineInAlarmState() ).
I would like to know if there is anything that allows me to satify this requirement:
I need to subscribe to an event with a filter and only receive a notification message when the condition is right (the filter criteria).
For example: I have 1000 data items or more from an event service but a client only wants to receive an event from certain data item (for example: item # 10 and its value > 10) .
The only way I can think of is somehow I need to be able to create an event or a subscription that I can specifiy which data item I need to receive an event from under certain condition (filter).
Thanks for any idea
