Syncfusion Wpf Datepicker

Implementing Syncfusion WPF DatePicker (SfDatePicker)

The SfDatePicker control allows users to select date values in a touch-friendly manner with a customizable dropdown date selector. This skill covers everything from basic setup to advanced customization and styling.

When to Use This Skill

• Basic date selection – Add a DatePicker control to your WPF application
• Date formatting – Display dates in various formats (short date, long date, month-only, etc.)
• Customizing the date selector – Modify cell templates, sizes, and spacing of the dropdown selector
• Styling and appearance – Change colors, backgrounds, themes, and flow direction (RTL support)
• Managing date values – Set, validate, and restrict date ranges; handle date change events
• Advanced interactions – Inline editing, watermarks, focus-based updates, keyboard input
• User-friendly UX – Implement null values, watermark text, and on-screen keyboard support

Quick Start

Basic DatePicker in XAML

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:syncfusion="http://schemas.syncfusion.com/wpf"
        Title="DatePicker Sample">
    <Grid>
        <syncfusion:SfDatePicker x:Name="sfDatePicker" 
                                 Width="200"
                                 Value="3/19/2026"/>
    </Grid>
</Window>

Basic DatePicker in C#

using Syncfusion.Windows.Controls.Input;

SfDatePicker sfDatePicker = new SfDatePicker();
sfDatePicker.Value = new DateTime(2026, 3, 19);
sfDatePicker.Width = 200;
this.Content = sfDatePicker;

Handle Date Selection

sfDatePicker.ValueChanged += (d, e) => 
{
    DateTime oldDate = (DateTime)e.OldValue;
    DateTime newDate = (DateTime)e.NewValue;
    Console.WriteLine($"Date changed from {oldDate:d} to {newDate:d}");
};

Common Patterns

Pattern 1: Set Date Format

<!-- Display as month only -->
<syncfusion:SfDatePicker FormatString="M" x:Name="sfDatePicker"/>

Pattern 2: Restrict Date Range

sfDatePicker.MinDate = new DateTime(2026, 1, 1);
sfDatePicker.MaxDate = new DateTime(2026, 12, 31);

Pattern 3: Allow Null with Watermark

<syncfusion:SfDatePicker AllowNull="True" 
                         Value="{x:Null}"
                         Watermark="Select a date"
                         x:Name="sfDatePicker"/>

Pattern 4: Inline Editing with Validation

<syncfusion:SfDatePicker AllowInlineEditing="True" 
                         InputScope="Number"
                         x:Name="sfDatePicker"/>

Pattern 5: Custom Styling with Colors

<syncfusion:SfDatePicker Foreground="Blue"
                         Background="LightGray"
                         AccentBrush="Green"
                         x:Name="sfDatePicker"/>
