RadMultiColumnComboBox provides flexible auto-completion options that suggests and appends text from the available in the list options as the user types.

The AutoCompleteMode property controls the auto-complete behavior and can be set to None, Suggest, Append and SuggestAppend:

  • None: Nothing happens when a user begins to type into the text box portion of the control.

  • Append: As the user types, the next item in the list that matches the user input is automatically appended to the characters the user has already typed. The popup is not shown without the user clicking the arrow.
