}

class Src 
{
    public DateTime? Lkuupaev { get; set; }
}

class ReportDialogForm : Form
{
    public ReportDialogForm()
    {
        var tb = new TextBox();
        Controls.Add(tb);
        var dtp = new MyDateTimePicker();
        dtp.Top = 30;
        var test = new Src();
        BindingSource BindingSource = new BindingSource();
        BindingSource.DataSource = test;
        BindingSource.ResetBindings(false);
        Binding b = new Binding("Value", BindingSource, "Lkuupaev");
        b.FormattingEnabled = true;
        dtp.DataBindings.Add(b);
        Controls.Add(dtp);

    }

    class MyDateTimePicker : DateTimePicker
    {
        public MyDateTimePicker()
            : base()
        {
            Format = DateTimePickerFormat.Short;
            ShowCheckBox = true;
            MinDate = new DateTime(1900, 1, 1);
            MaxDate = new DateTime(2900, 1, 1);
        }

        public new DateTime? Value
        {
            get
            {
                if (!this.Checked)
                    return null;
                return base.Value;
            }

            set
            {
                if (value != null)
                {
                    base.Value = (DateTime)value;
                    Checked = true;
                }
                else
                {
                    base.Value = DateTime.Today.AddDays(1);
                    base.Value = DateTime.Today;
                    Checked = false;
                }
