Split button in a tool window toolbar

Question

i'm writing a visual studio 2010 extension and got a ToolWindow with a ToolWindowToolbar.

in my toolbar i want to add a split button that while pressing the button (left part) will show the 'open file' dialog, and when pressing the arrow (right part) will show a list of recently opened files.

i have tried several ways to no avail, can you help?
