From: Gerhard on 7 Apr 2010 10:36
I am posting this again at request of Microsoft concierge.

I have downloaded and installed both VS2010 RC and Silverlight 4 RC. In
testing out functionality, I built a simple RIA Business Application against
the Chinook database. I have a datagrid with the albums, another datagrid
with the tracks that ties to the selected album, and a combobox that ties to
the selected album's artist. When I do my first filter (using the built in
filter text box), all works fine, but if I change the filter, the combobox no
longer stays in sync (the datagrid does though). Can you please help? XAML
is as follows:
