If you add these entries to an observablecollection and put that in application.current.resources.  Use that same observablecollection in both datagrids. 
When you add an entity in one DataGrid  then it will appear in the other one.
Although it is not really what the sample is about, you can see a simple way to  share an observable collection across views in this:

I don't quite follow where the selecting comes in with your code but that sample also uses the current item to share which is selected.
I also recommend wrapping an entity in a row viewmodel.
As I do in this:
