先引入命名空间 xmlns:my="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"，还要引入类库 PresentationFramework.Aero.dll ,PresentationFramework.dll PresentationCore.dll
效果图，后面背景是灰色的，所以你看combobox是灰色的，我样式设透明的了
先上传一张我的杰作吧，改造后的textbox，这里不想介绍了
一个带搜索功能和带条件搜索的文本框，同样你也可以改成 带搜索功能和带条件搜索的combobox
请调用这个
Style="{StaticResource CboCommomStyle}"
