Hi, i had a listbox will binding the data for price of the product. How can i calculate the total price of all of it?

My phone page.xaml is as below:

                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{Binding ProdId}"/>
                            <TextBlock Text="{Binding ProdPrice}"/>
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
</ListBox>

            Service1Client svc = new Service1Client();
            svc.GetAllModelsCompleted += new EventHandler<GetAllModelsCompletedEventArgs>(svc_GetAllModelsCompleted);
            svc.GetAllModelsAsync();
        }
        void svc_GetAllModelsCompleted(object sender, GetAllModelsCompletedEventArgs e)
        {
            listBox1.ItemsSource = e.Result;
        }
