Quick Start Example

Basic DatePicker Setup

XAML:

<Window
    x:Class="DatePickerDemo.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:editors="using:Syncfusion.UI.Xaml.Editors">
    
    <Grid>
        <editors:SfDatePicker 
            x:Name="datePicker"
            Header="Select Date"
            PlaceholderText="Choose a date"
            SelectedDate="2026-03-22"
            Width="250" 
            Height="75" />
    </Grid>
</Window>

C#:

using Syncfusion.UI.Xaml.Editors;

namespace DatePickerDemo
{
    public sealed partial class MainWindow : Window
    {
        public MainWindow()
        {
            this.InitializeComponent();
            
            // Creating an instance of the Date Picker control
            SfDatePicker sfDatePicker = new SfDatePicker();
            this.Content = sfDatePicker;
        }
    }
}

Common Patterns

Pattern 1: Date Range Restriction

<editors:SfDatePicker 
    x:Name="datePicker"
    MinDate="2026-01-01"
    MaxDate="2026-12-31"
    Header="Select date within 2026" />

Pattern 2: Blocking Specific Dates

// In ViewModel or code-behind
public DateTimeOffsetCollection BlockedDates { get; set; }

public void InitializeBlockedDates()
{
    BlockedDates = new DateTimeOffsetCollection();
    BlockedDates.Add(new DateTimeOffset(new DateTime(2026, 12, 25))); // Christmas
    BlockedDates.Add(new DateTimeOffset(new DateTime(2026, 1, 1)));   // New Year
}

<editors:SfDatePicker 
    BlackoutDates="{Binding BlockedDates}" />

Pattern 3: Custom Date Format

<editors:SfDatePicker 
    DisplayDateFormat="MMMM dd, yyyy"
    DayFormat="{}{day.integer}"
    MonthFormat="{}{month.full}"
    YearFormat="{}{year.full}" />

Pattern 4: Localized DatePicker with Calendar Type

<editors:SfDatePicker 
    CalendarIdentifier="HebrewCalendar"
    Language="he-IL"
    FlowDirection="RightToLeft" />

Pattern 5: Null Value Support

<editors:SfDatePicker 
    AllowNull="True"
    SelectedDate="{x:Null}"
    PlaceholderText="Select a date" />

Pattern 6: Immediate Selection (No Submit Button)

<editors:SfDatePicker 
    ShowSubmitButtons="False" />

// Mark booked dates as unavailable
var bookedDates = GetBookedDatesFromDatabase();
datePicker.BlackoutDates = new DateTimeOffsetCollection();
foreach (var date in bookedDates)
