How to bind List Data to combobox - c#-4.0

Question

I mae a WCF service that contain this method :
public List<LocationDB> GetLocation()
{
List<LocationDB> locations = null;
using (SqlConnection connection = new SqlConnection(conn))
{
using (SqlCommand command = new SqlCommand())
{
command.Connection = connection;
command.CommandText = string.Format("Select L_ID ,L_Name from Location");
connection.Open();
//code to fill the locations list..
my problem is when i want to bind the result from this method in my code i do the following.
void MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
client.GetLocationCompleted += new EventHandler<GetLocationCompletedEventArgs>(client_GetLocationCompleted);
client.GetLocationAsync();
}
}
and :
void client_GetLocationCompleted(object sender, GetLocationCompletedEventArgs e)
{
LocationCombo.ItemsSource = e.Result;
LocationCombo.SelectedValuePath =
LocationCombo.DisplayMemberPath =
}
and finally my LocationDB Class that is located in the App_code folder in the asp web site:
[DataContract]
public class LocationDB
{
[DataMember]
public int Lid { get; set; }
[DataMember]
public int SmId { get; set; }
[DataMember]
public string Lname { get; set; }
how can i bind the SelectedValePath and the DisplayMemberPath in code behind not in XAML.
Thanks

Answer 1

From what I can tell you already have everything you need although some of it needs to be in a different order.
void client_GetLocationCompleted(object sender, GetLocationCompletedEventArgs e)
{
LocationCombo.SelectedValuePath = "Lid";
LocationCombo.DisplayMemberPath = "Lname";
LocationCombo.ItemsSource = e.Result;
}

You should be able to set each of them to a string which represents the property (on the bject you're binding to) to use as the SelectedValuePath and DisplayMemberPath respectively:
LocationCombo.SelectedValuePath = "Lid";
LocationCombo.DisplayMemberPath ="Lname";
LocationCombo.ItemsSource = e.Result.ToList();
