Dependent DropDownList

Using VS 2005 - 2008 - 2010 - VB Sql Server 2005 - 2008 I'm trying to use dependent dropdownlist to populate 3 or more dowpdowns. This is a simple project, and the main purpose of the project is to create a demo to be used as a tool to understand the process flow. Look at the example at: [login to view URL] Using this example and FormView, I was able to create dependent dropdownlist and populate as required, in Insert Mode. Edit Mode didn't work and threw errors. Therefore I need to see a simple working example, with code commented enough to enable me to apply those techniques in my production project. You are to: 1. Create a simple project in VS 2008 VB 2. Create 3 or more dependent dropdownlist, using FormView 3. Create 2 example pages - One using Stored Procedure and one using SqlDataSource 4. Use Northwind DB for example purposes Please ask questions as necessary.....
