Question

我无法使用日期范围选择器显示一个日历。我不确定从哪里开始，因为当您想更改月份时，仅隐藏其他日历似乎不起作用。

我正在尝试使用daterangepicker创建简化的，适合移动设备的日期范围选择器。我可以这样做的一种方法是删除其中一个日历。这将使我在移动版本上有更多的空间，并使我可以在网站上查看大多数重要内容。

我正在尝试使用引导程序3来实现此目的。我还在后端使用ASP.NET MVC。

Answer 1

DateRangePicker（使用单个扩展日历选择日期范围）。我将附上一个链接，该链接将为您提供示例。

using System;

namespace CustomWebControls
{
    [Serializable]
    public struct DateRange
    {
        public static readonly DateRange EMPTY = new DateRange();

        readonly DateTime from;
        readonly DateTime to;


        public DateRange(DateTime from, DateTime to)
        {
            this.from = from;
            this.to = to;
        }


        public DateTime From
        {
            get { return from; }
        }

        public DateTime To
        {
            get { return to; }
        }

        public TimeSpan TimeSpan
        {
            get
            {
                return to - from;
            }
        }

        public bool Contains(DateTime time)
        {
            return from <= time && time < to;
        }

        public DateRange Include(DateRange otherRange)
        {
            return Include(otherRange.From).Include(otherRange.To);
        }

        public DateRange Include(DateTime date)
        {
            if (date < from)
                return new DateRange(date, to);
            else if (date > to)
                return new DateRange(from, date);
            else 
                return this;
        }

        /// <summary>
        /// Creates a one day (24 hr) long DateRange starting at DateTime
        /// </summary>
        public static DateRange CreateDay(DateTime dateTime){
            return new DateRange(dateTime, dateTime.AddDays(1));
        }

        #region operators and overrides
        public override int GetHashCode()
        {
            return from.GetHashCode() + 29*to.GetHashCode();
        }

        public override bool Equals(object obj)
        {
            if (ReferenceEquals(this, obj)) return true;
            if (!(obj is DateRange)) return false;
            DateRange dateRange = (DateRange) obj;
            if (!Equals(from, dateRange.from)) return false;
            if (!Equals(to, dateRange.to)) return false;
            return true;
        }


        public static bool operator == (DateRange d1, DateRange d2)
        {
            return d1.Equals(d2);
        }

        public static bool operator !=(DateRange d1, DateRange d2)
        {
            return !d1.Equals(d2);
        }
        #endregion

    }
}

DateRangePicker 这是重写Calendar的类。它具有两个属性，一个属性用于设置所选DateRange的样式，另一个属性用于存储所选DateRange。

using System.ComponentModel;
using System.Drawing;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace CustomWebControls
{
    /// <summary>
    /// An extended Calendar that can select DateRanges as well as Dates
    /// </summary>
    [DefaultProperty("Text")]
    [ToolboxData("<{0}:DateRangePicker runat="server"></{0}:DateRangePicker>")]
    public class DateRangePicker : Calendar
    {
        static readonly TableItemStyle defaultSelectedDateRangeStyle = new TableItemStyle();


        static DateRangePicker()
        {
            //initialise a default colour for defaultSelectedDateRangeStyle
            defaultSelectedDateRangeStyle.BackColor = Color.LightSteelBlue;
        }

        TableItemStyle selectedDateRangeStyle = defaultSelectedDateRangeStyle;

        protected override void OnDayRender(TableCell cell, CalendarDay day)
        {
            if (SelectedDateRange.Contains(day.Date))
            {
                cell.ApplyStyle(selectedDateRangeStyle);
            }
        }

        protected override void OnSelectionChanged()
        {
            base.OnSelectionChanged();

            bool emptyDateRange = SelectedDateRange == DateRange.EMPTY;
            bool dateRangeAlreadyPicked = SelectedDateRange.TimeSpan.TotalDays > 1;

            if (emptyDateRange || dateRangeAlreadyPicked)
            {
                SelectedDateRange = DateRange.CreateDay(SelectedDate);
                //save this date as the first date in our date range
            }
            else
            {
                SelectedDateRange = 
                  SelectedDateRange.Include(DateRange.CreateDay(SelectedDate));
                //set the end date in our date range
            }
        }

        //DateRange gets stored in the viewstate since
        //it's a property that needs to persist across page requests.
        <Browsable(false)>
        public DateRange SelectedDateRange
        {
            get { return (DateRange) (ViewState["SelectedDateRange"]??DateRange.EMPTY); }
            set { ViewState["SelectedDateRange"] = value; }
        }

        //SelectedDateRangeStyle goes into a private
        //variable since this property is designed.
        [Category("Styles")]
        [Description("The Style that is aplied to cells within the selected Date Range")]
        [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
        [NotifyParentProperty(true)]
        [PersistenceMode(PersistenceMode.InnerProperty)]
        public TableItemStyle SelectedDateRangeStyle
        {
            get { return selectedDateRangeStyle; }
            set { selectedDateRangeStyle = value; }
        }
    }
}
