Using the keyboard you can perform some of the most common tasks.
This section describes the keyboard shortcuts used by RadAutoCompleteBox.
Up: Navigates up through the items in the DropDown portion of the control.
Down: Navigates down through the items in the DropDown portion of the control.
Tab: Selects the highlighted item and loses the focus. If there is no suggested item just loses the focus.
Enter: Closes the DropDown if it is open and selects the currently highlighted item.
Escape: Closes the DropDown and deletes the last non autocompleted entered text.
When an item is selected with the keyboard, it should be scrolled into the viewport and made visible.
TabNavigationExtensions.IsTabStop attached property indicates whether RadAutoCompleteBox is included in the tab navigation cycle. Example 1 illustrates how to set that property in order to exclude the control from the tab navigation. The property is available since R3 2016.
