RangeCalendar

in namespace DotVVM.BusinessPack.Controls

Renders a calendar which lets the user to select the begin and end date.

Usage & Scenarios

Renders a Gregorian-style calendar control which lets the user to select two date, time or date and time values.

Sample 1: Basic Usage

The SelectedStartDate and SelectedEndDate properties represent DateTime values with the date range selected in the control.

page.dothtml
ViewModel.cs

<bp:RangeCalendar SelectedStartDate="{value: StartDate}"
                  SelectedEndDate="{value: EndDate}" />

<p>Selected dates: <dot:Literal Text="{value: StartDate}" FormatString="g" /> - <dot:Literal Text="{value: EndDate}" FormatString="g" /></p>

using System;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.RangeCalendar.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime StartDate { get; set; } = DateTime.Now.AddDays(-1);
        public DateTime EndDate { get; set; } = DateTime.Now.AddDays(1);
    }
}

Sample 2: Selection Bounds

You can use the MinDate and MaxDate properties to specify the minimum and maximum values for the selection.

page.dothtml
ViewModel.cs

<bp:RangeCalendar SelectedStartDate="{value: StartDate}"
                  SelectedEndDate="{value: EndDate}"
                  MinDate="{value: MinimumDate}"
                  MaxDate="{value: MaximumDate}" />

<p>Selected dates: <dot:Literal Text="{value: StartDate}" FormatString="g" /> - <dot:Literal Text="{value: EndDate}" FormatString="g" /></p>

using System;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.RangeCalendar.sample2
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime StartDate { get; set; } = DateTime.Now.AddDays(-1);
        public DateTime EndDate { get; set; } = DateTime.Now.AddDays(1);
        public DateTime MinimumDate { get; set; } = DateTime.Now.AddDays(-5);
        public DateTime MaximumDate { get; set; } = DateTime.Now.AddDays(5);
    }
}

Sample 3: Modes

You can use the Mode property to determine whether you want to select Date, Time or DateTime (a combination of date and time).

Even if you are in the Time mode, the control still requires the SelectedStartDate and SelectedEndDate properties to be bound to properties of DateTime type.

page.dothtml
ViewModel.cs

<bp:RangeCalendar SelectedStartDate="{value: StartDate}"
                  SelectedEndDate="{value: EndDate}"
                  Mode="Date" />

<bp:RangeCalendar SelectedStartDate="{value: StartDate}"
                  SelectedEndDate="{value: EndDate}"
                  Mode="Time" />

<bp:RangeCalendar SelectedStartDate="{value: StartDate}"
                  SelectedEndDate="{value: EndDate}"
                  Mode="DateTime" />

using System;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.RangeCalendar.sample3
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime StartDate { get; set; } = DateTime.Now.AddDays(-1);
        public DateTime EndDate { get; set; } = DateTime.Now.AddDays(1);
    }
}

Sample 4: Restrictions

If you require more granular control over what dates can be selected, you can use the Restrictions property. We currently support the following types of restrictions:

DayOfWeekRestriction - Allows to disable selection of a specific day of week. You can also specify the time interval you need to disable using the StartTime and EndTime properties.
DateRangeRestriction - Allows to disable a secific range of dates (one day, one month, etc.). You just need to set the StartDate and EndDate properties.

Restrictions can be combined with MinDate and MaxDate properties and are verified both on client-side and server-side.

page.dothtml
ViewModel.cs

<bp:RangeCalendar SelectedStartDate="{value: StartDate}"
                  SelectedEndDate="{value: EndDate}"
                  Restrictions="{value: Restrictions}" />

using System;
using DotVVM.BusinessPack.Controls;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.RangeCalendar.sample4
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime StartDate { get; set; } = DateTime.Now.AddDays(-1);
        public DateTime EndDate { get; set; } = DateTime.Now.AddDays(1);

        public List<CalendarRestrictionBase> Restrictions { get; set; } = new List<CalendarRestrictionBase>()
        {
            new DayOfWeekRestriction() { DayOfWeek = DayOfWeek.Saturday },
            new DayOfWeekRestriction() { DayOfWeek = DayOfWeek.Sunday },
            new DateRangeRestriction() { StartDate = DateTime.MinValue, EndDate = DateTime.Now }
        };
    }
}

Sample 5: Format Strings

The FormatString property specifies the format that will be used to display selected dates. Use standard or custom .NET date format strings.

The language of the calendar and the first day of week is specified by the request culture. You can find more info in the Globalization tutorial.

page.dothtml
ViewModel.cs

<bp:RangeCalendar SelectedStartDate="{value: StartDate}"
                  SelectedEndDate="{value: EndDate}"
                  SelectionCompleted="{command: SelectionCompleted()}" />

<p>Date range selection has changed {{value: DateSelectionsCount}} times.</p>

using System;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.RangeCalendar.sample5
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime StartDate { get; set; } = DateTime.Now.AddDays(-1);
        public DateTime EndDate { get; set; } = DateTime.Now.AddDays(1);
        public int DateSelectionsCount { get; set; }

        public void SelectionCompleted()
        {
            DateSelectionsCount++;
        }
    }
}
