How to add events in .NET MAUI Switch (SfSwitch)?

This section illustrates how to add events in the .NET MAUI Switch control.

StateChanged Event

The StateChanged event triggers when the value or state of the IsOn property changes, either by tapping the switch button or programmatically setting the IsOn property. It provides access to the current and previous values through the SwitchStateChangedEventArgs object.

XAML

<syncfusion:SfSwitch StateChanged="SfSwitch_StateChanged"/>

C#

private async void SfSwitch_StateChanged(object sender, SwitchStateChangedEventArgs e)
{
    bool? newValue = e.NewValue;
    bool? oldValue = e.OldValue?;

    await DisplayAlert("Alert", "Switch State Changed", "close");
}

Output

StateChanging Event

The StateChanging event fires when the IsOn property’s state is about to change. It allows you to cancel the event if necessary, through the SwitchStateChangingEventArgs object.

XAML

<syncfusion:SfSwitch StateChanging="SfSwitch_StateChanging"/>

C#

private void SfSwitch_StateChanging(object sender, SwitchStateChangingEventArgs e)
{
    bool? newValue = e.NewValue;
    bool? oldValue = e.OldValue;

    if (newValue == null)
    {
        e.Cancel = true;
    }
}
