推荐答案

你需要使用这个类AdvancedComboBox：ComboBox而不是你的ComboBox控件。此方法称为子类，您可以查看如何执行此操作：

You need to use this class AdvancedComboBox : ComboBox instead of your ComboBox Control. This method is called "Subclassing" and you can take a look how to do it:

我宁愿简单地使用一个地方在WinForm中持有并在源代码中创建一个控件，如下所示：

I would rather simply use a place holder in the WinForm and create a control in the source code like this:

Dim oCmbBox As AdvancedComboBox = New AdvancedComboBox()

然后你可以使用占位符的坐标将它移动到正确的位置......

Then you can move it on the right place using the coordinates of the place holder ...
