Filter Performance on a column with unique values

I currently have a DataGrid bound to an ObservableCollection with about a dozen columns of various types.  The ObservableCollection contains about 20,000 rows.  When I filter "between" on a column of type Double  (i.e. >1.02 and <1.03) that contains mostly unique values, I am finding it is taking over a minute to apply the filter.  Is there something that I can do to speed this up?

Hi Todd,

Sorry for the inconvenience caused. We have tested the reported issue in different scenario but we are unable to reproduce the issue. Could you please check the below sample?

Sample: GDC_ScrollingPerformance.zip

We suspect you are using our grid in some other scenario, So If possible could you please modify our sample and revert us with replication procedure, that would be very helpful to resolve your problem earlier.

Please let know if you have any queries.
