Properties Group

Answer : Properties group in usercontrol

The type of the property should support a TypeConverter.

For in the image you showed above, Padding struct supports PaddingConverter:

If a usercontrol has a property
public MyPoint mypoint { get; set;}
then

[TypeConverter(typeof(MyPointConverter))]
public struct MyPoint
{
...
}

public class MyPointConverter : TypeConverter
{
...
}
