Q:

Silverlight Combobox Binding to Element

I have a silverlight telerik RadComboBox. I am designing a master detail page. 
In the grid I have list of people - one of the columns in the grid is Salutation.
when i click on an item in the grid all the textboxes below fill according to their binding.
But with the combobox I am wondering if you can bind it like this.
 SelectedItem="{Binding ElementName=PersonGrid, Path=SelectedItem.SalutationLookupValue, Mode=TwoWay}"

Im guessing that you cannot do it this way. I would like to do it this way but im thinking that I need to bind the selecteditem to SelectedSalutation and set that when the selected item is set for the grid..
    public Person SelectedPersonResult
    {
        get { return _selectedPersonResult; }
        set
        {
            SetObject(ref _selectedPersonResult, value, "SelectedPersonResult");
            if (_selectedSalutationResult != null)
            {
                SelectedSalutation = SalutationList.Where(x => x.Value == SelectedPersonResult.SalutationLookupValue).FirstOrDefault();
            }
        }
    }

again Id prefer to do it the first way (within the xaml) but Im guessing that doing it the second way is the only way?

A:

If that ComboBox of yours behaves like the standard one the first method should work, but you should not bind to SelectedItem, the right property would be SelectedValue. (Does that combobox have such a property?)
