We're developing a MVVM Prism SL app against RIA. So we're not using the DomainDataSource element in XAML.
All the examples seem to show client side paging. With this type of paging all the records are returned from the server and the paging control simply hides the records not shown in a page.
We want to implement server side paging so that if we have a million rows, then only the "PageSize" number of records are returned.
It also appears that setting a GroupDescriptor in XAML does not work if paging is implemented, without paging it works fine. Additionally it does appear that the PageSize is not respected if the user manually groups by a column when paging is implemented. Can you check this?
Can you give me an example of how server paging should work against a RIA DataContext when using the MVVM pattern, using your DataGrid? Also how will it work if Grouping is implemented.
