Ideas for Quick Hierarchical Listing - .NET

I have a table in SQL Server listing corporate departments and their sections and subsections (3 levels). I would like to create some web-based listing of this, b开发者_高级运维ut similar to a TreeList.

I was thinking to set up nested Ajax Accordions, but it was taking me way too long to put together. I would even settle for a GridView with non-repeating column values.

Is there a way I can implement my idea without it taking me more than an hour or so for a newbie to complete? Any controls in ASP.NET or Ajax I can bind to would be great.

Thanks to Ozzy, I was able to solve this simple issue using a TreeList. Since my issue is simlper than the one in the tutorial he supplied, all I did was create DataTable for each level, and for each row I added the TreeNode (which was simply the string value of that entry). Thanks!!
