What is HexIdOfGrid?

Then you are not using the correct HDC.

Try using GetWindowRect() instead, using the grid's HWND.

Again, you do not need to access the individual pixels.  Once you have
a suitable HDC, you can BitBlt() or StretchBlt() the entire window to
a bitmap, and then use that as needed.  For example:

    ImageClassPointer->Picture->Bitmap->Width = width;
    ImageClassPointer->Picture->Bitmap->Height = height;
    ::BitBlt(ImageClassPointer->Canvas->Handle, 0, 0, width, height,
DCToTheGrid, 0, 0, SRCCOPY);
