如何在没有设置值的情况下将剑道日期选择器（弹出日期视图）设置为特定年份（1435）（希望值为空）

Question

我使用两个 kendo datepicker 制作自定义 mvc 控件，以在部分视图中显示（gregi 和 hijri）日期，如果我更改任何一个的日期，它会将另一个更改为等效日期

导致剑道限制处理回历日历我进行了一些修改以显示正确的日期我使用文化并将最大日期设置为回历为 29/12/1600

如果我将 value(DateTime.Now) 设置为回历日历，一切正常

但我希望它显示空值和用户选择值，但如果我删除值并且当用户打开日历时年份显示为 1600，我想显示 1435 并保持值为空

她是我的密码

Controller
    public class UserControl_GHDate
    {
        public DateTime? GregiDate { get; set; }
        [Column(TypeName = "DateTime2")]
        public DateTime? HijriDate
        {
            get
            {
                if (GregiDate==null)
                {
                    return null;//DateTime.Now; 
                }
                else
                {
                    return GregiDate;
                }


            }
            set {  }
        }

我认为剑道日期选择器有一个最小值选项尝试指定最小值为 1435 年
