I have developed one, but it doesn’t inherit from ComboBox. It’s a custom control (inherits from Control), that uses a TextBox, a Button, and a Form with a ListBox (the dropdown part). And you can use it as a CellViewer/CellEditor.
I have to say, it’s a complicated thing to make. I can’t give you the control in its current form, because it’s specifically designed to be used in our framework (our company creates custom .NET applications). The naming scheme of our code is also a bit weird for outsiders, so it wouldn’t fit in your application.
But I’ll try to create a new version, that can be used externally.
