you should use OwnerDrawn techniques like the one described here: https://stackoverflow.com/questions/2891981/net-ownerdraw-combobox-vista-7-themed-dropdownlist

or you override the window proc and redefine whole control message handling or you create your own control from scratch or you use third party controls like DevExpress WinForms suite or Telerik ones.
