Answer 2:

看看这个链接：

http://www.eidias.com/Blog/2012/2/20/customizing-wpf-combo-box-style

这是关于如何使一个自定义的组合框的示例代码一个博客。 自定义组合框，他正在看起来非常像一个你需要的。 因此，我认为这将是对你非常有用。

Answer 3:

这里是WPF组合框一个完整的风格。 这也很容易定制。

http://www.wpfhelper.com/index.php/styles-in-wpf/combobox/15-combobox-style-in-wpf

该代码是很长，所以我不会张贴他们都在这里。 然而，这是基础组合框样式：
