How to disable the past dates in the Kendo date picker?

Question

How to disable the past dates in the Kendo date picker ? ( Date Picker validation)

That will allow the user to select only the current date and future date.

In the HTML :
@Html.EditorFor(Model => Model.AppointmentDate)

In the JQuery :
$('#AppointmentDatee').data('kendoDatePicker')

Answer 1

The shortest way to disable past dates is using min parameter with current date value:

var presentDate = new Date();

$(function () {
    var datepicker = $('#AppointmentDate').kendoDatePicker({
        value: presentDate,
        min: presentDate,
    }).data('kendoDatePicker');
});

If you're using Razor with @Html.Kendo() helper, use DatePickerBuilderBase.Min() method:

@(Html.Kendo().DatePicker().Name("AppointmentDate").Min(DateTime.Today))

However, the min parameter will remove all disabled past dates (i.e. they're not shown in calendar view). If you want to show disabled dates but the user cannot interact with them (by clicking the date), use k-state-disabled CSS class in empty option inside month parameter:

var datepicker = $('#AppointmentDate2').kendoDatePicker({
        value: presentDate,
    min: presentDate,
    month: {
        empty: '<div class="k-state-disabled">#= data.value #</div>'
    }
}).data('kendoDatePicker');

If @(Html.Kendo()) helper is used, use DisabledDates to call a function which disables past dates like example below:

<script>
var getPastDates = function(begin, end) {
    for (var dtarr = [], date = start; date < end; date.setDate(date.getDate() + 1)) {
        dtarr.push(new Date(dt));
    }

    return dtarr;
}

function disablePastDates(date) {
    var pastDate = getPastDates(new Date('0001-01-01T00:00:00Z'), new Date());
    if (date && compareDates(date, dates)) {
        return true;
    } 
    else {
        return false;
    }
}

function compareDates(date, dates) {
    for (var i = 0; i < dates.length; i++) {
        if (dates[i].getDate() == date.getDate() &&
            dates[i].getMonth() == date.getMonth() &&
            dates[i].getYear() == date.getYear()) {
            return true;
        }
    }
}
</script>

Helper usage:

@(Html.Kendo().DatePicker().Name("AppointmentDate").DisableDates("disablePastDates"))
