Hi to all,
I have a lookup combobox the ItemsSource is populated through a [DataContract] in a WCF Service. The ComboBox has a DisplayMemberPath property (which I use to define which field to show) but does NOT have a ValueMemberPath property (as other Comboboxes do). How, then, can I define the field that shall assign the value of the control? Some people seem to use the ItemsSource property and give it a {Binding}, that seems to work, but as I have to assign these bindings in my code (Completed-Event when the data arrived from the WCF service) how could I do this? Who has done a similar thing before me?

This is my event to populate the ComboBox

private void proxy_GetAllKeyArtikelBestellbarCompleted(object sender, GetAllKeyArtikelBestellbarCompletedEventArgs e)
{
	if (e.Result != null)
	{
		this.cboKeyArtikelBestellbar.ItemsSource = e.Result;

In XAML the Combobox looks like this

<ComboBox Grid.Column="1" Grid.Row="1" 
          x:Name="cboKeyArtikelBestellbar" 
          Width="130" 
          HorizontalAlignment="Left"
          DisplayMemberPath="Bestellbar"
          SelectedItem="{Binding Path=IdKeyArtikelBestellbar}"
          >

But this last attribute (SelectedItem) is not working. Anyway the Item would be a whole set of fields, not just a Binding Path...
How to?
