How to Save Editing on Back Button Press in the .NET MAUI Image Editor (SfImageEditor)

The Syncfusion® .NET MAUI Image Editor (SfImageEditor) provides support for saving edits when the back button is pressed. This demonstration helps you understand how to implement this functionality using the ToolbarItemSelected event handler.

XAML:

Initialize the Image Editor control.

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

C#:

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

this.imageEditor.ToolbarItemSelected += OnToolbarItemSelected;

C#:

In the OnToolbarItemSelected method, check the toolbar item’s Name property for “Back” and call the SaveEdits method to save changes when the “Back” button is clicked.

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

Output:

Save edits on back button press (Crop).
