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')

Solution

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"))

Working examples:

JSFiddle demo 2 (grayed-out past dates)

Can you provide snippet of the Kendo date picker code? At least it should comply with minimal reproducible example.

@TetsuyaYamamoto, sorry for that. please take a look on the syntax

[Tetsuya Yamamoto]

I think easier to use Html.Kendo().DatePicker().Min(DateTime.Now) or Html.Kendo().DatePicker().Min(DateTime.Today). Also I want to ask this: are you want to hide all disabled past dates or just show but disable click on them?

[goofyui]

Either way , it is fine. Objective is to select either today’s or future date. Not the past date. I was hoping to make the changes on html editor . Having kendo datepicker syntax actually changes the date format or design format.

[Tetsuya Yamamoto]

I decided to include both of them (hiding all past dates & grayed-out disabled dates). The implementation parts are somewhat similar, just with little difference.

Best well detailed explanation;
