Maui Nullable and Clearable DateTimePicker

The Nullable DateTimePicker is a custom calendar control for selecting a nullable date and time value in a .NET MAUI application. It provides a consistent and platform-independent user interface for selecting dates, and allows the user to clear the value if needed.

This control uses the <a href="https://github.com/CommunityToolkit/Maui" target="_blank">CommunityToolkit.Maui</a> Popup.

Usage

To use the Nullable DateTimePicker control in your .NET MAUI application, follow these steps:

1- Add the NullableDateTimePicker control to your XAML layout file:

xmlns:ndtp="clr-namespace:Maui.NullableDateTimePicker;assembly=Maui.NullableDateTimePicker" <pre> <code> <ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:ndtp="clr-namespace:Maui.NullableDateTimePicker;assembly=Maui.NullableDateTimePicker" x:Class="Maui.NullableDateTimePicker.Samples.MainPage"> </code> </pre>

2- Bind the DateTime? value property to a property in your view model: <pre> <code> <ndtp:NullableDateTimePicker NullableDateTime="{Binding MyDateTime}" Mode="Date" /> </code> </pre>

3- Add .UseMauiCommunityToolkit() to the MauiProgram.cs file in your project. <pre> <code> public static MauiApp CreateMauiApp() { var builder = MauiApp.CreateBuilder(); builder .UseMauiApp<App>() .UseMauiCommunityToolkit() .... </code> </pre>

More examples, please see the samples project

Options

NullableDateTimeChanged Event

The NullableDateTimeChanged event is used to indicate when a NullableDateTime value has been changed. This event is commonly used in programming or software environments and is triggered when the NullableDateTime value is modified.

The event utilizes the DateTimeChangedEventArgs class as its argument. The DateTimeChangedEventArgs class contains additional information that is carried at the moment the event is triggered. It may include details about the date and time change, such as the old DateTime value and the new DateTime value.

Below is an example code snippet illustrating the usage of the "NullableDateTimeChanged" event and the "DateTimeChangedEventArgs" argument class: <pre> <code> NullableDateTimePicker dateTimePicker = new NullableDateTimePicker(); dateTimePicker.NullableDateTimeChanged += OnNullableDateTimeChanged;

private static void OnNullableDateTimeChanged(object sender, DateTimeChangedEventArgs e) { Console.WriteLine("DateTime changed!"); Console.WriteLine("Old DateTime: " + e.OldDateTime); Console.WriteLine("New DateTime: " + e.NewDateTime); } </code> </pre>
