    <ComboBox HorizontalAlignment="Left" IsEditable="True" IsTextSearchEnabled="True" ItemsSource="{Binding customerCollection}" SelectedItem="{Binding SelectedCustomer}" SelectedValuePath="CustomerId" DisplayMemberPath="Name" Margin="183,146,0,0" VerticalAlignment="Top" Width="120" RenderTransformOrigin="0.514,0.39"/>

MVVM代码

public class CustomerModel
{
    public int CustomerId { get; set; }
    public String Name { get; set; }
}
public class CustomerViewModel
{
    public CustomerViewModel()
    {
        customerCollection = new ObservableCollection<CustomerModel>();
        customerCollection.Add(new CustomerModel() { CustomerId = 1, Name = "A" });
        customerCollection.Add(new CustomerModel() { CustomerId = 2, Name = "AA" });
        customerCollection.Add(new CustomerModel() { CustomerId = 3, Name = "AAA" });
        customerCollection.Add(new CustomerModel() { CustomerId = 4, Name = "BAAA" });
        customerCollection.Add(new CustomerModel() { CustomerId = 5, Name = "BB" });
        customerCollection.Add(new CustomerModel() { CustomerId = 6, Name = "CC" });
        customerCollection.Add(new CustomerModel() { CustomerId = 7, Name = "CCCC" });
        customerCollection.Add(new CustomerModel() { CustomerId = 8, Name = "DFF" });
        customerCollection.Add(new CustomerModel() { CustomerId = 9, Name = "ABC" });
    }
    public ObservableCollection<CustomerModel> customerCollection { get; set; }
    private CustomerModel _SelectedCustomer = new CustomerModel();
    public CustomerModel SelectedCustomer
    {
        get { return _SelectedCustomer; }
        set
        { _SelectedCustomer = value; }
    }
}

不幸的是，在组合框控件中没有这样的内置属性。但是，您可以使用此autocomplete textbox/combobox user control来实现此目的。
