DatePicker

in namespace DotVVM.BusinessPack.Controls

Renders a calendar allowing users to select year, month or full date.

Usage & Scenarios

Renders a text field that allows the user to enter or select date using a Gregorian-style calendar popup.

Sample 1: Basic Usage

The SelectedDate property represents a Date value with a date selected in the control.

page.dothtml
ViewModel.cs

<bp:DatePicker SelectedDate="{value: SelectedDate}" />

<p>Selected date: <dot:Literal Text="{value: SelectedDate}" FormatString="g" /></p>

using System;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DatePicker.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime SelectedDate { get; set; } = DateTime.Now;
    }
}

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:DatePicker SelectedDate="{value: SelectedDate}"
               MinDate="{value: MinimumDate}"
               MaxDate="{value: MaximumDate}" />

<p>Selected date: <dot:Literal Text="{value: SelectedDate}" FormatString="g" /></p>

using System;
using DotVVM.Framework.ViewModel;

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

Sample 3: 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.
DateRangeRestriction - Allows to disable a specific range of dates (one day, one month, etc.). You just need to set the StartDate and EndDate properties, where the StartDate represents inclusive start of the restriction and EndDate represents exclusive end of the restriction.

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

page.dothtml
ViewModel.cs

<bp:DatePicker SelectedDate="{value: SelectedDate}"
               Restrictions="{value: Restrictions}" />

<p>Selected date: <dot:Literal Text="{value: SelectedDate}" FormatString="g" /></p>

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

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DatePicker.sample3
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime SelectedDate { get; set; } = DateTime.Now;

        public List<DateRestriction> Restrictions { get; set; } = new List<DateRestriction>()
        {
            //These will prevent saturdays and sundays from being selected
            new DayOfWeekRestriction() { DayOfWeek = DayOfWeek.Saturday },
            new DayOfWeekRestriction() { DayOfWeek = DayOfWeek.Sunday },
            //This will prevent selection of all dates from the 1st of June to the 6th of June of current year
            new DateRangeRestriction() 
            { 
                StartDate = new DateTime(DateTime.Today.Year, 6, 1), 
                EndDate = new DateTime(DateTime.Today.Year, 6, 7)
            }
        };
    }
}

Sample 4: Format Strings

The FormatString property specifies the format that will be used to display selected date. 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:DatePicker SelectedDate="{value: SelectedDate}"
               FormatString="dd MMM yyyy"/>

<p>Selected date: <dot:Literal Text="{value: SelectedDate}" FormatString="g" /></p>

using System;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DatePicker.sample4
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime SelectedDate { get; set; } = DateTime.Now;
    }
}

Sample 5: Inline

The 'ShowInline' property toggle whether the DatePicker is displayed inline in page or as a drop-down editor.

page.dothtml
ViewModel.cs

<bp:DatePicker SelectedDate="{value: SelectedDate}"
               ShowInline />

<p>Selected date: <dot:Literal Text="{value: SelectedDate}" FormatString="g" /></p>

using System;
using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DatePicker.sample5
{
    public class ViewModel : DotvvmViewModelBase
    {
        public DateTime SelectedDate { get; set; } = DateTime.Now;
    }
}
