QuestionIs it possible to do event handling in the ViewModel? Pin

I have the following code in Code-Behind section of my WPF MVVM:

public EquipmentIdentity()
        {
            InitializeComponent();
            EquipmentIdentityViewModel eivm = new EquipmentIdentityViewModel();
            DataContext = eivm;
            dataPager.OnDemandLoading += dataPager_OnDemandLoading;
        }

private void dataPager_OnDemandLoading(object sender, Syncfusion.UI.Xaml.Controls.DataPager.OnDemandLoadingEventArgs args)
        {
            //some codes here
        }


How can I remove this event handling from Code-Behind and take it to the ViewModel?

When I use dataPager.OnDemandLoading += dataPager_OnDemandLoading; in ViewModel it shows this error:

Quote:
System.NullReferenceException: 'Object reference not set to an instance of an object.'
