Basically, you need to pass IEnumerable result of the actual query to the database to initialize the ObservableCollection :

var linqResults = sql.Staff_Time_TBLs
                     .Where(staff => staff.Staff_No == SelectedEmployee.Key &&
                                     staff.Date_Data == filterFrom &&
                                     staff.Date_Data == filterTo);

var observable = new ObservableCollection(linqResults);
