how do I make a scrollable List of entry widgets in gtksharp?

I'm trying to make a scrollable list of entry widgets, because I have an unknown number of entry widgets, and don't want them to go off the window, I've tried a few things, like a ScrolledWindow, which I think can only contain one object, so I tried using a Vbox container, which just resulted in a black box with the entry widgets in, but it just packed the entry widgets closer together as I added more instead of keeping them spaced apart but letting me scroll through them, I tried a TreeView, which just resulted in a blank box with none of the widgets showing, and I made a scrollbar, but I have no idea how I even make the scrollbar do anything, does anyone know how I can make it work?
