Derived ListView Class to eliminate Flickering.

[Jose Fuentes]

Hello,
**

I'm trying to eliminate the listview flicker. A created a class derive
from listview and set the properties for optimizeddouble buffer etc.

*********
public ref class myFFlistview : System::Windows::Forms::ListView
{
public:
myFFlistview(void);
};

myFFlistview::myFFlistview(void)
{
this->SetStyle(ControlStyles::OptimizedDoubleBuffer |
ControlStyles::AllPaintingInWmPaint, true);
}

I used this class in my project by changing the current list view that i
had in the designer to my type:

//System::Windows::Forms::ListView^ ThelistView;

myFFlistview^ ThelistView;

//this->ThelistView = (gcnew //System::Windows::Forms::ListView());

this->ThelistView = (gcnew myFFlistview());

**The project compile and build and was tested everything works, without
flickering. But when i try to open the designer i can't see any of the
GUI.
Just this message:
**

Is there another way to set the optimized double buffer or cast the
listview at runtime so I can still have the designer available for other
people to see.

Thanks
