Yes. The provided example works perfectly.
However, based on some condition, I still can't figure out what's exactly works wrong.
But during expanding ComboBox it raises ToString() method for each Route inside RouteList collection.
Since, ToString() returns me Id (GUID), I see GUID value, instead of Name.
If instead of returning Id I'll return Name in ToString() method, everything will work perfectly, but, that's not a solution of the issue.
