Wpf 如何更改切换按钮所在组合框上默认显示的组合框颜色？ 这是我更改切换按钮所在组合框颜色的代码- #FF928B81 #FFC3C3 #FFF1F1 #0073b0 #FF004165 #FFa4ddfa

问题是在点击切换按钮时会显示更改后的颜色，但我希望更改后的颜色默认显示在组合框中，切换按钮所在的组合框中？我尝试了很多我的代码中已经存在的东西，请建议我应该做什么？

您需要在样式-

ComboBoxToggleButton

This is my code to change the color of combo box box in which toggle button is located-
