The DropDown control allows developers to build ANY custom comboboxes, drop-down and auto-complete controls with literally few lines of code.

The Demo Kit contains source code of several ready-to-use controls including auto-complete tool, drop-down treeview, grid, tabbed dialog, etc.

The control is inherited from the panel control. And it can be used as container or stand-alone drop-down button or the role of drop-down button can be delegated to another control.
