31 May 20229 minutes to read

This section explains about the date selection in WinUI Calendar Date Picker control and how to restrict or limit the users to select date within a range.

Select the date

You can set or change the selected date programmatically by using SelectedDate property. By default, SelectedDate property value is null.

MainWindow.xaml.cs

SfCalendarDatePicker sfCalendarDatePicker= new SfCalendarDatePicker();
sfCalendarDatePicker.SelectedDate = new DateTimeOffset(new DateTime(2021, 01, 06));

NOTE

Download demo application from GitHub.

You can also change the selected date interactively by selecting a date from the drop-down calendar or by entering the date value in editor of Calendar Date Picker. You can get the selected date from the SelectedDate property.

Limit available dates

You can restrict the users from selecting a date within the particular range by specifying MinDate and MaxDate properties. The default value of MinDate property is 1/1/1920 and MaxDate property is 12/31/2120.

NOTE

Dates that appears outside the minimum and maximum date range will be disabled (blackout).

MainWindow.xaml

<calendar:Calendar x:Name="sfCalendarDatePicker"/>

MainWindow.xaml.cs

SfCalendarDatePicker sfCalendarDatePicker = new SfCalendarDatePicker();
sfCalendarDatePicker.MinDate = new DateTimeOffset(new DateTime(2021, 01, 5));
sfCalendarDatePicker.MaxDate = new DateTimeOffset(new DateTime(2021, 01, 24));

NOTE

When MinDisplayMode property value is set to Year and MinDate value is set to 15/01/2021, selecting the month of the minimum date will set the starting date value from the minimum date, i.e., from January 15, 2021.

NOTE

The MinDate property value should not be greater than the MaxDate property value.

Block dates using BlackoutDates

You can block particular dates from the date selection by adding respective dates in the BlackoutDates collection property. The default value of BlackoutDates property is null.

ViewModel.cs

public class ViewModel
{       
    public DateTimeOffsetCollection BlockedDates { get; set; }
    public ViewModel()
    {
        BlockedDates = new DateTimeOffsetCollection();
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 17)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 4)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 2, 5)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 2, 6)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 9)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 3, 11)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 13)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 4, 14)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 18)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 5, 19)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 26)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 6, 29)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 31)));
        BlockedDates.Add(new DateTimeOffset(new DateTime(2021, 1, 27)));
    }
}

MainWindow.xaml

<calendar:SfCalendarDatePicker  
                     x:Name="sfCalendarDatePicker"
                     BlackoutDates="{Binding BlockedDates}">
    <calendar:SfCalendarDatePicker.DataContext>
        <local:ViewModel/>
    </calendar:SfCalendarDatePicker.DataContext>
</calendar:SfCalendarDatePicker>

MainWindow.xaml.cs

sfCalendarDatePicker.DataContext = new ViewModel();
sfCalendarDatePicker.BlackoutDates = (sfCalendarDatePicker.DataContext as ViewModel).BlockedDates;

Disable dates dynamically (All weekend days)

You can prevent the users from selecting any dates or days (example: all weekend days) by handling the CalendarItemPrepared event and setting ItemInfo.IsBlackout property value as true for those specific dates.

NOTE

You can also change the text displayed for specific days or dates in the drop-down calendar by using the ItemInfo.DisplayText property.

MainWindow.xaml

<calendar:SfCalendarDatePicker x:Name="sfCalendarDatePicker"
                               CalendarItemPrepared="SfCalendarDatePicker_CalendarItemPrepared"/>

MainWindow.xaml.cs

SfCalendarDatePicker sfCalendarDatePicker = new SfCalendarDatePicker();
sfCalendarDatePicker.CalendarItemPrepared += SfCalendarDatePicker_CalendarItemPrepared;

You can handle the event as follows:

MainWindow.xaml.cs

private void SfCalendarDatePicker_CalendarItemPrepared(object sender, CalendarItemPreparedEventArgs e)
{
    //Block all weekend days
    if (e.ItemInfo.ItemType == CalendarItemType.Day &&
        (e.ItemInfo.Date.DayOfWeek == DayOfWeek.Saturday ||
        e.ItemInfo.Date.DayOfWeek == DayOfWeek.Sunday))
    {
        e.ItemInfo.IsBlackout = true;
    }
}

        (e.ItemInfo.Date.DayOfWeek == DayOfWeek.Saturday ||
        e.ItemInfo.Date.DayOfWeek == DayOfWeek.Sunday))
