TreeView supports keyboard navigation which provides an effective way to navigate through the TreeView control, simply by using the defined keys when required. By default, the keyboard navigation functionality is enabled in TreeView. However, you can disable it by setting KeyboardNavigation property of the C1TreeView class to false.
