asp .net & treeview

is there any way to add some component like treeview or tabstrip
in asp .net ( web application )

i'm new at asp .net and really don't know if it is possible.

i tried to add treeview with <object> tag in my aspx file, in design time it shows the treeview but i can't write code for it.

also i find that u can add treeview to global.asax file , but i don't know next step.

I also copied windows.systems.forms dll to my bin directory of webserver.

these are some steps that i checked but didn't work out.
