React Calendar Props

The value of this option will be passed to the accesskey attribute of the HTML element that underlies the widget.

This option is used when the widget is displayed on a platform whose guidelines include the active state change for widgets.

Without a value, the widget cannot detect its format. In this case, specify the dateSerializationFormat option that supports the following formats:

• "yyyy-MM-dd" - a local date

• "yyyy-MM-ddTHH:mm:ss" - local date and time

• "yyyy-MM-ddTHH:mm:ssZ" - the UTC date and time

• "yyyy-MM-ddTHH:mm:ssx" - date and time with a timezone

This option applies only if the forceIsoDateParsing field is set to true in the global configuration object.

This option accepts an array of dates...

$(function () {
    $("#calendarContainer").dxCalendar({
        // ...
        disabledDates: [ new Date("07/1/2017"),  new Date("07/2/2017"), new Date("07/3/2017") ]
    });
});

... or a function that specifies whether the currently checked date is disabled.

$(function () {
    $("#calendarContainer").dxCalendar({
        disabledDates: function (args) {
            var dayOfWeek = args.date.getDay(),
                month = args.date.getMonth(),
                isWeekend = args.view === "month" && (dayOfWeek === 0 || dayOfWeek === 6 ),
                isMarch = (args.view === "year" || args.view === "month") && month === 2;

            if(isWeekend || isMarch) {
                return true;
            }
        }
    });
});

When this option is set to true, the widget text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

DevExpress.config({
    rtlEnabled: true
});
