Hi, Artem, 

RadDateTimePicker offers the CalendarSize property which allows you to specify the size of the calendar in the drop down.

As to the minimum/maximum size of the drop down, you can use the following code snippet: 

            RadDateTimePickerCalendar calBehavior = this.radDateTimePicker1.DateTimePickerElement.CurrentBehavior as RadDateTimePickerCalendar;
            calBehavior.DropDownMinSize = new Size(300, 300);
            calBehavior.DropDownMaxSize = new Size(600,600);

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Thank you for the answer!

I've already tried this solution, but it didn't work. I lost opportunity to resize calendar at all.

Hello, Artem,

Indeed, the user is allowed to shrink the width, but not the height. 

I have logged it in our feedback portal by creating a public thread on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use the following code snippet:

        public RadForm1()
        {
            InitializeComponent();
            //this.radDateTimePicker1.CalendarSize = new Size(500, 500);


            
            RadDateTimePickerCalendar calBehavior = this.radDateTimePicker1.DateTimePickerElement.CurrentBehavior as RadDateTimePickerCalendar;
            calBehavior.DropDownSizingMode = SizingMode.UpDownAndRightBottom;
            calBehavior.DropDownMinSize = new Size(400, 400);
            calBehavior.DropDownMaxSize = new Size(600, 600);

           this.radDateTimePicker1.Opened+=radDateTimePicker1_Opened;
        }

        private void radDateTimePicker1_Opened(object sender, EventArgs e)
        {
            RadDateTimePickerCalendar calBehavior = this.radDateTimePicker1.DateTimePickerElement.CurrentBehavior as RadDateTimePickerCalendar;
            calBehavior.PopupControl.MinimumSize= calBehavior.DropDownMinSize;
        }

Should you have further questions please let me know.
