Hello Mike,

I have been searching for a solution for your issue and I can suggest you handle the ‘Closed’ event of the ‘MainWindow’ of your WPF application  to call the ‘SaveCustomization’ method in its body.

So your customizations will be automatically saved in a layout file (.xml) each time when you close the application. For example :

private void Window_Closed(object sender, EventArgs e)

        {

            using (FileStream fs = new FileStream("xamDataGridLayout1.xml", FileMode.Create, FileAccess.Write))

            {

                this.xamDataGrid1.SaveCustomizations(fs);

            }

        }

If you require any further assistance, please do not hesitate to ask.
