The enclosed Web Form and Web User Controls are from a .NET
Web application I've been developing to track my employment
search.

editForm_Contact.aspx hosts the edit_contact and 
list_contactType User Controls. 

edit_contact.ascx is a DataGrid which allows editing in-line. 
list_contactType.ascx is a drop-down control containing 
contact types (Employer, Facility, etc.). The drop-down acts 
as a filter to the DataGrid.

A user selects a contact type from the drop down. When the
"submit" event is triggered on the Web Form, the value for
contact_type is set in a property on the User Control which
hosts the DataGrid, effectively filtering the results to be
displayed.
