How do I programmatically list/enumerate the web sites in IIS from a c#
application?
I want to know which host headers each site responds to.

unbound DropDownList SelectedIndexChanged not firing
10/10/2008 11:00:28 PM
I have a DropDownList which is originally bound to a SqlDataSource. In
Design view, the control is shown as "Databound".
Later I changed my mind and changed the dropdown binded to a datatable
programmatically. In Design view, the control is shown as "Unbound". The
poblem is: after the change, the SelectedIndexChanged event no longer fires.
