After loading your EasyObject you can filter (temporarily hide) rows. To disable the filter set this property to String.empty. After applying a filter, using Iteration via MoveNext will properly respect any filter you have in place. See also Sort.
For a detailed explanation see the RowFilter property on ADO.NET's DataView.RowFilter property.
emps.Filter = "City = 'Berlin'";
