Good Morning,

I have a combobox in c#, and I need change the border color of drop down list,

How I can do this?

推荐答案

你需要自定义绘制它 - 标准的ComboBox不允许你自定义下拉列表的外观。



这个例子可能对你有所帮助：



外观可自定义组合框 [ ^ ]



但我不知道它是否允许更改下拉列表，或仅更改文本框部分。



一般来说，这很难做到，而且可能需要很长时间来弄清楚并进行排序。你确定它值得花时间吗？

You need to custom draw it - the standard ComboBox doesn''t allow you to customize the appearance of the drop down list.

This example might be of help to you:

Appearance Customizable ComboBox[^]

But I don''t know if it even allows changes to the drop down list, or only to the textbox part.

Generally, this is quite hard to do, and it''ll probably take you a long time to figure out and get sorted. Are you really sure that it''s worth the time?
