MSDN style treeview + splitter ? (newbie)

[Andy Mackie]

Any suggestions on how to do an MSDN library style of page using ASP.NET
webforms ?

On the left I want a treeview, separated with a splitter from result grids
on right. I've downloaded and installed the IE WebControls which contain a
treeview. My initial thoughts were that this needs some form of frames, but
are frames something of a no-go with ASP.NET ?

Any suggestions on how to do this ?

Thanks,
Andy Mackie
