Windows Presentation Foundation (WPF)
Have you actually done any WinForms programming? Have you used the DataGirdView?
The DataGirdView "Allow(s) the user to sort (ascending/descending) by clicking on the column header. Provide(ing) a visual clue as to how the sorting is done in the column header. (It) Do(es) this without round tripping to the server".
Do you know what "disconnected data access" means?
Do you undestand that you can sort datatables / dataviews? (without "round tripping").
