You could cast the SelectedItem property of the ComboBox to a CUSTOMER object to get the currently selected item:

CUSTOMER selectedCustomer = C1.SelectedItem as CUSTOMER;
if(selectedCustomer != null)
    MessageBox.Show(selectedCustomer.CUSTOMER_NAME);

To select an item you set the SelectedItem property to a CUSTOMER object that is included in the ComboBox's ItemsSource:

C1.SelectedItem = C1.Items[0]; //selects the first customer (index = 0)

Or if you know the name or description of the customer:

string theName = "some customer name...";
C1.SelectedItem = C1.Items.OfType().FirstOrDefault(x => x.CUSTOMER_NAME == theName);
