I want to disable list items in a .Net 2003 Web based Drop Down List control. How can I do that server side? I do not want to display a blank item. I do that now and our QA says I need to display -Select and Item- instead. Additionally, they say that while -Select an Item- is the first item displayed and therefore selected, once a user selects another choice I should not allow them to return to the -Select an Item-. None of the selectable list items is permitted to be the default.

ie
-Select an Item- (disabled)
Item 1
Item 2
Item 3
Item 4
