Answer 1

The best way to do this is in your viewmodel.

You should bind the SelectedItem of your datagrid to a new property in your ViewModel. In the set method of this new Property, call a new method to populate a new ObservableCollection/List/whatever…

Finally, bind your “other grid” ItemsSource to this new observable collection from your ViewModel.

Edit:
If you need to load one thing or another depending on the column you are going to use the code behind, take a look at this:
