Structure of SfDatePicker

WPF DatePicker Control

Assembly deployment

Refer to the control dependencies section to get the list of assemblies or NuGet package that needs to be added as a reference to use the control in any application.

You can find more details about installing the NuGet package in a WPF application in the following link:

How to install nuget packages

Add control through designer

The SfDatePicker control can be added to an application by dragging it from the toolbox to a designer view. The following required assembly references will be added automatically:

  • Syncfusion.SfInput.WPF
  • Syncfusion.SfShared.WPF

WPF DatePicker Added by Designer

Adding control manually in XAML

To add the control manually in XAML, follow the given steps:

  1. Add the following required assembly references to the project:
    • Syncfusion.SfInput.WPF
    • Syncfusion.SfShared.WPF
  2. Import Syncfusion WPF schema in the XAML page.
  3. Declare the SfDatePicker control in the XAML page.

    <Window xmlns=""
            Title="SfDatePicker Sample" Height="350" Width="525">
            <!-- Adding SfDatePicker control -->
            <syncfusion:SfDatePicker x:Name="sfDatePicker" 

Add control manually in C#

To add the control manually in C#, follow the given steps:

  1. Add the following required assembly references to the project:
    • Syncfusion.SfInput.WPF
    • Syncfusion.SfShared.WPF
  2. Import the SfDatePicker namespace using Syncfusion.Windows.Controls.Input;.
  3. Create an SfDatePicker instance, and add it to the window.

    using Syncfusion.Windows.Controls.Input;
    namespace SfDatePickerSample {    
        public partial class MainWindow : Window {
            public MainWindow() {
                //Creating an instance of SfDatePicker control
                SfDatePicker sfDatePicker = new SfDatePicker();
                //Adding SfDatePicker as window content
                this.Content = sfDatePicker;

Setting the Date

We can set or change the selected date by using Value property. If we not assign any value for the Value property, it will automatically assign the current system date as Value property value.

<syncfusion:SfDatePicker  Value="5/30/2021"
                          Name="sfDatePicker" />
SfDatePicker sfDatePicker= new SfDatePicker();
sfDatePicker.Value = new DateTime(2021,5,30);

WPF DatePicker Date Setting

Date changed notification

When the selected date of SfDatePickeris changed, it will be notified by using the ValueChanged event. You can get the details about the checked item in ItemCheckedEventArgs.

  • OldValue : Gets a date which is previously selected.

  • NewValue : Gets a date which is currently selected.

<syncfusion:SfDatePicker ValueChanged="SfdatePicker_ValueChanged" 
SfDatePicker sfDatePicker = new SfDatePicker();
sfDatePicker.ValueChanged += SfdatePicker_ValueChanged;

You can handle the event as follows:

private void SfdatePicker_ValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) {          
    Console.WriteLine("The Old selected Date: " + e.OldValue.ToString());
    Console.WriteLine("The Newly selected Date: " + e.NewValue.ToString());            

Display the date using the FormatString

We can edit and display the selected date with various formatting like date, month and year formats by using the FormatString property. The default value of FormatString property is "d".

<syncfusion:SfDatePicker x:Name="sfDatePicker" 
SfDatePicker sfDatePicker = new SfDatePicker();
sfDatePicker.FormatString = "M";

WPF DatePicker FormatString

Specifying format for the DateSelector

We can allow the user to select the pair of date, month and year selector or any single selector cell from the SfDateSelector by using the SelectorFormatString property. The default value of SelectorFormatString property is "M/d/yyyy" and the date, time and year value selector is enabled in the SfDateSelector.

<syncfusion:SfDatePicker x:Name="sfDatePicker" 
SfDatePicker sfDatePicker = new SfDatePicker();
sfDatePicker.SelectorFormatString = "M";

WPF DatePicker Month Selector
Here, we can only able to select the month value from the SfDateSelector

Set selected value on lost focus

If we want to update the selected date of SfDateSelector to the SfDatePicker.Value property by moving the focus from SfDateSelector to anywhere, use the SetValueOnLostFocus property value as true. By default, the selected date of SfDateSelector can be sets to the SfDatePicker.Value property only by clicking the OK button, otherwise the selected value not updated by the move focus.

<syncfusion:SfDatePicker  SetValueOnLostFocus="True"
                          Name="sfDatePicker" />
SfDatePicker sfDatePicker= new SfDatePicker();
sfDatePicker.SetValueOnLostFocus = true;

Localization support

Localization is the process of translating the application resources into different language for the specific cultures. You can localize the Ok and Cancel button text in SfDatePicker control by adding resource file for each language.


Refer Localization page to know more about how to provide a localization support for the SfDatePicker.


SfDatePicker supports various built-in themes. Refer to the below links to apply themes for the SfDatePicker,
