How to convert events into commands in .NET MAUI ListView (SfListView)?

The .NET MAUI ListView allows you to convert the events into commands using Behaviors to follow the MVVM pattern.

C#
To achieve this, need to create a command for the ItemTapped event of the SfListView in the ViewModel.

public class ContactsViewModel : INotifyPropertyChanged
{
    #region Properties

    public Command<Syncfusion.Maui.ListView.ItemTappedEventArgs> tapCommand;

    public Command<Syncfusion.Maui.ListView.ItemTappedEventArgs> TapCommand
    {
        get { return tapCommand; }
        set { tapCommand = value; OnPropertyChanged("TapCommand"); }
    }

    #endregion

    #region Constructor

    public ContactsViewModel()
    {
       TapCommand = new Command<Syncfusion.Maui.ListView.ItemTappedEventArgs>(OnTapCommand);
    }

    private void OnTapCommand(Syncfusion.Maui.ListView.ItemTappedEventArgs obj)
    {
        var name = (obj.DataItem as Contacts).ContactName;
        var number = (obj.DataItem as Contacts).ContactNumber;
        App.Current.MainPage.DisplayAlert(name, "Number:" + number, "Ok");
    }

XAML

Associate the command to the appropriate event of SfListView using Behaviors, as shown below.

<syncfusion:SfListView x:Name="listView" >
 <syncfusion:SfListView.Behaviors>
   <local:EventToCommandBehavior EventName="ItemTapped"
                                 Command="{Binding TapCommand}">
   </local:EventToCommandBehavior>
 </syncfusion:SfListView.Behaviors>
</syncfusion:SfListView>

Now, when an item in the ListView is tapped, the corresponding Command in the ViewModel will be invoked automatically, performing the desired operation, as illustrated in the screenshot.
