DropDownButton outside of a Toolbar

[segfault]

Is it possible in .NET to easily make a drop down button control, such as you might find in a toolbar, but in another location on a form?

To be more precise, what I want is a button with two functions, depending on which part is clicked. The greatest area is on the left side, represented by the icon for the button, and has the default action. A small sliver on the right side of the button is represented by a drop down arrow, and presents a menu when clicked.

This is very intuitive behaviour, and I really want to use it in an application, but the only control I can find with this behaviour is the toolbarbutton control
