Multiline treeview possible?

Can anyone think of a way or point me in the right direction to be able to
get a multiline treeview? By this I mean that each TreeNode Label can span
say 2 lines (delimited by \n)?

Thanks!

Just to clarify with a bit of an example:
+ John Doe
Widgets Inc.
-Home Contact
-Work Contact
+ Jane Doe
SomeCo.
-Headoffice Contact
-International Contact

In this case treeNode1.Text = "John Doe\nWidgets Inc.", with 2 child nodes
beneath it; treeNode2.Text = "Jane Doe\nSomeCo.", also with 2 child nodes.
Make sense?

Thanks :-)

Hey guys, I posted this message a few days ago and got no response.. I'm
hoping that someone has at least played with this or can give me some
advice.

Thanks again,
Dan

Hi Dan!

I want to show you an example. I haven't checked for errors, but can give
you an Idea. Hope it helps.

Hi Hans,
Thanks for the reponse, but thats similar to what I tried before (that being
using a '\n' in the treeNode.Text field). What you end up with is a []
looking character (one of the weird unicode boxes) and everything still on a
single line (except for the child nodes of course being a level deeper). Any
other ideas? Is there perhaps a way for me to easily inherit the
functionality of the treeview into a control of my own and just rewrite the
way it renders text? I have no clue where to even begin with this approach,
so any help would certainly be appreciated!

Cheers,
Dan
