Usage & Scenarios

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

HTML Rendered by the Control

Sample 1: Basic Usage

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

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

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

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DateTimePicker.sample1
{
    public class ViewModel
    {
        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.

<bp:DateTimePicker SelectedDate="{value: SelectedDate}"
                   MinDate="{value: MinimumDate}"
                   MaxDate="{value: MaximumDate}" />

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

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DateTimePicker.sample2
{
    public class ViewModel
    {
        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: 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 SelectedDate property to be bound to a property of DateTime type.

<bp:DateTimePicker SelectedDate="{value: SelectedDate}"
                   Mode="Date" />

<bp:DateTimePicker SelectedDate="{value: SelectedTime}"
                   Mode="Time" />

<bp:DateTimePicker SelectedDate="{value: SelectedDateTime}"
                   Mode="DateTime" />
using System;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DateTimePicker.sample3
{
    public class ViewModel
    {
        public DateTime SelectedDate { get; set; } = DateTime.Now;
        public DateTime SelectedTime { get; set; } = DateTime.Now;
        public DateTime SelectedDateTime { get; set; } = DateTime.Now;
    }
}

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.

<bp:DateTimePicker SelectedDate="{value: SelectedDate}"
                   Restrictions="{value: Restrictions}" />
using System;
using DotVVM.BusinessPack.Controls;

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

        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 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.

<bp:DateTimePicker SelectedDate="{value: SelectedDate}"
                   FormatString="dd MMM yyyy"
                   Mode="Date" />

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

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

Sample 6: SelectionCompleted Event

When the user completes or changes the selection, the SelectionCompleted event is triggered.

<bp:DateTimePicker SelectedDate="{value: SelectedDate}"
                   SelectionCompleted="{command: SelectionCompleted()}" />

<p>Date has been changed {{value: DateSelectionsCount}} times.</p>
using System;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DateTimePicker.sample6
{
    public class ViewModel
    {
        public DateTime SelectedDate { get; set; } = DateTime.Now;
        public int DateSelectionsCount { get; set; }

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

Sample 7: Keep Popup Open

The ClosePopupOnSelectionComplete can keep the popup open when the date is selected. By default, the popup closes when the user finishes the date selection.

<bp:DateTimePicker SelectedDate="{value: SelectedDate}"
                   ClosePopupOnSelectionComplete="false" />

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

namespace DotvvmWeb.Views.Docs.Controls.businesspack.DateTimePicker.sample7
{
    public class ViewModel
    {
        public DateTime SelectedDate { get; set; } = DateTime.Now;
    }
}
