SelectedValuePath does not return an id

Question

Hey I have a question about getting an ContactTypeId from the ContactType. This is the object that has an id:

public class ContactType
{
    public int ContactTypeId { get; set; }

    public string ContactTypeValue { get; set; }

    public int ContactId { get; set; }

    public DateTime? Added { get; set; }
    public DateTime? Updated { get; set; }
    public DateTime? Deleted { get; set; }

}

I wrote a WPF application that has a listbox.

<ComboBox x:Name="ContactTypeComboBox" HorizontalAlignment="Left"     Margin="110,68,0,0" VerticalAlignment="Top" Width="120" ItemsSource="{Binding ContactTypes}" DisplayMemberPath="ContactTypeValue" SelectedValuePath="ContactTypeId"  />

If i get Selected value path doesn't give an ContactTypeId from that object. It only gives a string "ContactTypeId"

Please help me to get a ContactTypeId from ContactType

SelectedValuePath tells the control how to drill down into the selected item and extract a value. The value for the selected item (in this case, its ContactTypeId) is exposed as SelectedValue. That's the property you want to read.
