The RadDateRangePicker control supports keyboard navigation using the tab or arrow keys:
Tab key Navigation - Once focus is on the RadDateRangePicker control, the popup Calendar is automatically opened. The
SHIFT+TABkey combination move between the StartDatePicker and the EndDatePicker controls. When the PopUpButtons of the embedded pickers are shown they are also being focused by pressing the
SHIFT+TAB. The first time the user presses the TAB key, focus moves to the first date input area, where the user can type a start date value.
Arrow key Navigation - Users can navigate within the input areas of the embedded RadDatePicker controls using the arrow keys:
The left and right arrow keys move the cursor one position to the left or right. When the shift key is pressed at the same time, the left and right arrow keys extend or contract the current selection on position to the left or right.
The up and down arrow keys increase or decrease the value of the date part that contains the cursor when the [StartDatePicker/EndDatePicker].DateInput.IncrementSettings.InterceptArrowKeys property is true. The [StartDatePicker/EndDatePicker].DateInput.IncrementSettings.Step property specifies the number of months, days, years, hours, minutes or seconds by which the value changes.
