One new feature added to the textbox control is the ability to specify custom auto complete sources for textboxes (for browsers that support autocomplete of course). By creating an AutoCompleteStringCollection, which is just a simple collection, and by binding it to the AutoCompleteCustomSource property of the textbox you can specify where the browser pulls its autocomplete list from. In order to do this you must also set the AutoCompleteSource property to CustomSource. You can also specify any of the builtin sources such as AllUrl, FileSystem, HistoryList, etc. This could prove to be a useful feature for internal applications.
