Combo box Navigation

VB.NET (Dreamweaver MX)

I need to create a web form which contains multiple combo boxes which allow users to navigate to particular records. e.g

One combo has a list of staff members. When the user chooses a member of staff they are redirected to a detail record for that member.

Another combo will have a list of Customers and when a user chooses a customer from the list they are redirected to a detail record for that customer.

I dont wish to use a form with a submit button. I would like to redirect the users when they make a choice from the combo.

How can I do this?

Thanks in Advance

On the boxes, put autopostback = true and them just write events for the onSelectionChange
