The WinForms Autocomplete component allows users to enable autocompletion functionality for any edit control. Multiple columns with a header in the autocomplete pop-up provide information for each matching entry. Its rich, built-in feature set includes different autocompletion modes such as suggest and append, appearance customization, and more.
The autocomplete control auto appends the top most item in the list to the text box.
An external datasource can be specified to be used as the history list.
