AspNet 2.0 Treeview Control VB.NET - HELP

[jamie]

Hi,
I hava a sql server with 3 tables in it the first table is self
referencing and one other looks up this table and the last table.

Table1:
StateID|ParentStateID|State|

Table2:
TeamID|StateID|Team|TypeID|

Table3:
TypeID|Type|

I need to take the data from these tables on put it into a
TreeviewControl. So that the treeview look something like:

COUNTRY
|___
STATE
|
|__
TYPE
|
|__
TEAM
TEAM
TEAM

Any help on how to do this would be gratefully recieved

Thanks in advance
Jamie
