Question

In my winform, I have three group boxes, based on selection of the
items in a combobox the second group box(at the center)
is hidden using groupbox.visible property.
The problem is when the second goupbox is hidden, there
seems to be an empty space in the area of the hidden group box,
I want to move the third group box to the place where second
group box is present. Can I use any other control instead of group box?

Answer 1

You could manually set Location and Size properties of your third groupbox or (I think better) set Dock property of both groupboxes to Top, so when your second gb becomes not visible, the third should scroll up to occupy free space.
