DropDownButton Popup Location

[Leandro]

Hey, is there a way to change the popup location of RadDropDownButton? I'm currently trying to put it over the button and at the right side. See screenshot to know what I mean. It's is not showing correctly because the edge of the screen. 

I've tried setting the popup bound but it don't work

btnOpcoesTela.DropDownButtonElement.DropDownMenu.PopupOpened += DropDownMenu_PopupOpened;
private void DropDownMenu_PopupOpened(object sender, EventArgs args)
        {
            var popup = sender as RadDropDownButtonPopup;

            popup.SetBounds(10, 5, popup.Width, popup.Height);

        }
