TAutoComplete is an extended ActiveTextBox that provides a list of suggestions on the current partial word typed in the textbox. The suggestions are requested using callbacks. The Frequency and MinChars properties sets the delay and minimum number of characters typed, respectively, before requesting for sugggestions. An embedded TRepeater is used to Display the list of suggestions. It can be accessed and styled through the Suggestions property and its sub-properties.
On each request for suggestions, the OnSuggestion event will be raised. The event handler receives the entered token that can be used to build the list of suggestions and to dataBind() it to the Suggestions repeater.
When a suggestion is selected the OnSuggestionSelected event is raised, with the index of the selected suggestion contained in the parameter. Multiple selections can be performed in the same textbox. The selections must be separated by any characters specified with the Separator property.
