問題就迎刃而解了： http://textuploader.com/?p=6&id=mQ9u – 2013-03-26 16:39:10

你應該去到MSDN網站，並獲得了組合框的默認控件模板。之後，您可以在您的項目中使用它並根據您的需要進行更改。在這裏：ComboBox ControlTemplate Example

要麼或者使用Expression Blend的

下面的圖片是我的XAML的結果。 http://i.stack.imgur.com/L8jpj.png 有點難以實現您的MSDN模板的願望結果。 MY XAML CODE：在<文本框X http://textuploader.com/?p=6&id=yWl7a – 2013-03-26 12:44:09

：名稱= 「PART_EditableTextBox」（...）的一部分，您的foregroung值從「{StaticResource的前景}「到」白色「，我認爲這就是你想要的 – Santux 2013-03-26 13:49:54

該文本的顏色更改爲白色。並且在LostFocus上，背景和前景都是白色的:)我想在Onfocus上看到白色的前景，但是在失去焦點上看到黑色。 – 2013-03-26 14:06:28
