This demo illustrates how to apply the following DateRangeBox settings:
-
value An array where you can specify the selected range (start/end dates). The DateRangeBox also allows you to define start/end dates separately. For this purpose, use the startDate and endDate properties instead.
-
displayFormat Date display format. You can use one of our predefined formats or specify a custom format as needs dictate. This demo illustrates the latter.
-
disabled
Specifies whether the DateRangeBox responds to user interaction. -
showClearButton Displays a button that clears DateRangeBox values.
-
multiView Switches between our single-month and two-month dropdown calendar.
-
applyValueMode
Defines whether the selected value is applied instantly or after a user clicks the Apply button.
