I'm attempting to use a Silverlight ComboBox with a static list of elements in a very simple binding scenario. The problem is the selected item is not returning me the Text of the TextBlock within the ComboBox and is instead returning "System.Windows.Controls.TextBlock".

My XAML is:

<ComboBox SelectedValue="{Binding Country, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnExceptions=True}">
    <TextBlock FontSize="11" Text="Afghanistan" />
    <TextBlock FontSize="11" Text="Albania" />
    <TextBlock FontSize="11" Text="Algeria" /> 
</ComboBox>

In my C# file I'm binding to the ComboBox using:

Customer customer = new Customer() { Country = "Albania" };
DataContext = customer;

The binding does not result in Albania as the selected country and updating the ComboBox choice results in the Country being set to "System.Windows.Controls.TextBlock". I've tried fiddling around with DisplayMemberPath and SelectedValuePath but haven't found the answer. I suspect it's something really simple I'm missing.
