Why VS designer doesn't work with sub classes ?

[Ky Nam]

Hi For example : Class Parent Private Class Child Inherits System.Windows.Forms.UserControl End Class End Class VS designer doesn't work with class Child Is there anyway to load designer for Child ?

[Christian Graus]

No, I don't think so. Why would you want to embedd a user control class ?

I need it is Private , Child is used by Parent only

The designer will not look for classes embedded in other classes. You also cannot do what you want, because the designer can't get at the private class to create an instance of it. Your UserControl class must be made Pblic for it to work in the designer. You can try breaking it out into a seperate class (both of your classes in the same file) and tagging it a Friend, but I have my doubts on it working. This is because a Friend class is visible only to other code in the same assembly, not outside the assembly. I'm guessing this would preclude the designer from seeing the class.
