Embedding Editfields in ArrayCtrl offers nice editing and filtering capabilities, and the function

Ctrl<EditField>()

offers a fast way to do it but.... it has also a couple of caveats :

1 - Embedded fields get frames, which is ugly inside the array
2 - Embedded fields grab ArrayCtrl rightclick context menu

This simple template solves both :

template<class E> class Embedded : public E
{
	protected:

		void RightDown(Point p, dword keyflags)
		{
			Ctrl *c = this;
			ArrayCtrl *a;
			while( (c = c->GetParent()) != NULL && ((a = dynamic_cast<ArrayCtrl *>(c)) == NULL))
				;
			if(a)
			{
				Rect cRect = E::GetScreenRect();
				Rect aRect = a->GetScreenRect();
				p.y += cRect.top - aRect.top - a->HeaderObject().GetHeight();
				p.x += cRect.left - aRect.left;
				a->RightDown(p, keyflags);
			}
		}
		
	public:
		typedef Embedded<E> CLASSNAME;
		
		Embedded<E>() { E::ClearFrames(); }
};

It's usage is simple, just define your ctrl as, for example :

typedef Embedded<EditDouble> EditDoubleEmbedded;

Then use as a normal editfield in arrayctrl.
The field will get no frames and forward context menu clicks to its ArrayCtrl container.
