The DataGrid data source is in ObservableCollection. If not applied datagrid.items.refresh method, the view is not updated fast enough as the data is real time signal with about a hundred per seconds. But if applied the refresh method, the CPU consumes more than 50%.

Any suggestion?

Thanks,

OK, I removed the Refresh method and used the event base class which implement INotifyPropertyChanged interface.

The CPU consuming is improved to about 35% to 41%. But still a little high.
