Implementing DateTimeEdit (WPF)

An enhanced date-time input control with mask editing, calendar/clock dropdown, date range restriction, formatting, and MVVM binding support.

When to Use This Skill

Use this skill when the user needs to:

Add a date/time picker input field to a WPF application
Bind a selected date to a ViewModel property (DateTime two-way binding)
Format the displayed date/time (predefined patterns or custom patterns)
Restrict selectable dates with min/max range or blackout dates
Enable inline editing (mask mode or free-form text editing)
Show a calendar, clock, or combined dropdown picker
Display watermark text when no date is selected
Handle null date values
Apply locale-specific date formats via CultureInfo
Localize dropdown button labels (Today/None)

Component Overview

Class	Namespace	Assembly

Quick Start Example

<!-- MainWindow.xaml -->
<Window xmlns:syncfusion="http://schemas.syncfusion.com/wpf">
    <Window.DataContext>
        <local:ViewModel/>
    </Window.DataContext>
    <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
        <syncfusion:DateTimeEdit DateTime="{Binding SelectedDate, Mode=TwoWay}"
                                 Pattern="ShortDate"
                                 MinDateTime="01/01/2020"
                                 MaxDateTime="12/31/2030"
                                 Height="25" Width="200"
                                 Name="dateTimeEdit"/>
    </StackPanel>
</Window>

// ViewModel.cs
public class ViewModel : NotificationObject
{
    private DateTime _selectedDate = DateTime.Now;
    public DateTime SelectedDate
    {
        get => _selectedDate;
        set { _selectedDate = value; RaisePropertyChanged(nameof(SelectedDate)); }
    }
}

Common Patterns

Scenario	Properties / Approach
Two-way date binding	`DateTime="{Binding SelectedDate, Mode=TwoWay}"`
Show calendar + clock	`DropDownView="Combined" Pattern="FullDateTime"`
Free-form text editing	`CanEdit="True"`
Date-only range restriction	`MinDateTime="..." MaxDateTime="..."`
Allow null / clear value	`IsEmptyDateEnabled="True" NullValue="{x:Null}" ShowMaskOnNullValue="False"`
Watermark when null	Add `NoneDateText="Select a date"` alongside null value properties
Custom date display	`Pattern="CustomPattern" CustomPattern="dd-MMM-yyyy"`
Culture-aware formatting	`CultureInfo="fr-FR" Pattern="FullDateTime"`
Read-only input	`IsReadOnly="True"`
RTL layout	`FlowDirection="RightToLeft"`
Apply theme	`SfSkinManager.SetVisualStyle(dte, VisualStyles.FluentLight)`
