The Syncfusion .NET MAUI Image Editor (SfImageEditor) provides support to save editing on the back button press. The following demonstration helps you to understand how to save editing on the back button press using ToolbarItemSelected event handler.

XAML:

Initialize the ImageEditor control.

<imageEditor:SfImageEditor x:Name="imageEditor" Source="image.png">
</imageEditor:SfImageEditor>

C#:

Initiate the ToolbarItemSelected event handler and subscribe the OnToolbarItemSelected method to the event.

private void OnToolbarItemSelected(object sender, ToolbarItemSelectedEventArgs e)
{
   if (e.ToolbarItem != null && e.ToolbarItem.Name.Equals("Back", StringComparison.InvariantCultureIgnoreCase))
