ASP.Net Populate A Treeview From A Database

I have an Access database table of customers names and other details. Some of them have ParentID fields that reference other users in the table. What I want to do is create a TreeView control on a form that populates depending on which customer ID is selected (via a textbox or listbox or somesuch control). The idea being that the Root node will consist of 1 customer, and there will be up to (but not always) 5 levels of child nodes from this. I will try to show this with a brief diagram (apologies for ASCII artwork) User 1 | |-- User 4 | | | |----User 11 | |----User 14 | | | |----User 21 | | | |---- User 34 | | | |--- User 22 | | | |----User 23 |-- User 5 | |----User 17 | | | |--- user 26 | |----User 19 I want classes writing for: 1) The query of the database 2) The population of the Treeview 3) The returning of how many customers are children of the root. 4) The returning of which generation a specific user ID is in relation to the root (1 - 5) 5) A routine that returns a value of 1 for the root nodes first child, and .1 for each other generation of child after 1. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
