RadAutoCompleteTextView has three different modes for providing suggestions.
The suggest mode can be changed with the
setSuggestionMode method of the TKAutoCompleteTextView. The default value is
this.autocomplete.SuggestMode = SuggestMode.Suggest;
SuggestMode.SUGGEST mode the autocomplete represents the filtered suggestions, matching the typed text, in a pop-up view, which contains list of the suggestions.
SuggestMode.APPEND mode the autocomplete shows only the first suggestion matching the typed text, which is represented as direct suffix of the typed text.
SuggestMode.SUGGEST_APPEND mode the autocomplete combines both upper-mentioned modes. It shows all matching suggestions in a pop-up view and the first of them is appened to the typed text.
