Clear dataset then refill

Dear The Expert,
I am creating a serial communication application by using vb.net, after the data received then they will be proceed and then show on the datagrid, I show them by using below commands:

mydataset.clear
mydataadapter.fill(mydataset)

the above commands will clear all contents in mydataset and then refill them, I think this will takes a lot of resources. is there another way for doing this?

Thanks

Other than disposing the dataset and creating new one , I can't think of another way . But , Clear method is absolutely perfect for this matter .

You can clear individual datatables in the dataset if that works for you. Might be less intensive if you have a lot of datatables and only need some refreshed.
