(I'll assume you are referring to ASP.net because there is no dropdown list control in windows forms)

On the first two DDLs you use the SelectedIndexChanged event handler to get the data and populate the appropriate downstream dropdown list. The first two controls must have their "AutoPostback" attribute set to True so that changing items in the drop down list in the client browser will actually cause a postback to happen.
