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}"
