I may be wrong but I think you will have to remove them from designer and within the loop you have, add for each button, the coordinates you require them on the panel or whatever view they are to be on. In some ways you have more control if you declare the items in code especially if their relative positions follow a mathematical algorithm.
i.e. Button(i).left=200dip or Button(i).left=i*56dip. etc. etc.
