Syncfusion has it on their multi select control, can you guys at it to Asp.Net core for us?

Please, change in link: https://docs.telerik.com/kendo-ui/knowledge-base/calendar-select-dates-click

Instead of:

var clickedDateString = clickedItem.children("a")[0].title;

var clickedDate = new Date(clickedDateString);

This:

var clickedDate = kendo.calendar.toDateObject(clickedItem.children("a"))

And add:

calendar.trigger('change');

Hello Viktor,

Sorry, I missed it

$('#calendar').data('kendoCalendar').selectWithoutCtrlKey();

The function call for the calendar is more convenient

Hello Viktor,

Thanks, but this not work, i am change function:

kendo.ui.Calendar.prototype.selectWithoutCtrlKey = function() {
        var me = this;

        this.element.on("mousedown",
            "td",
            function(e) {
            
                // get item if the user clicked on an item template
                var clickedItem = $(e.target).closest("td[role='gridcell']");

                // prevent click event for item elements
                // todo: think about multiple add event
                clickedItem.on("click",
                    function(e) {
                        e.stopPropagation();
                        e.preventDefault();
                    });

                if (clickedItem.length > 0) {
                    var clickedDate = me._toDateObject(clickedItem.children("a"));

                    var selectedDates = me.selectDates();

                    if (clickedItem.hasClass("k-state-selected")) {
                        // if date is already selected - remove it from collection
                        selectedDates = $.grep(selectedDates,
                            function(item, index) {
                                return clickedDate.getTime() !== item.getTime();
                            });
                    } else {
                        selectedDates.push(clickedDate);
                    }


                    me.selectDates(selectedDates);
                    me.trigger('change');
                }
            });
    };
