WinForms Data Grid - Asynchronous detail view loading

This example demonstrates how to load detail data in a background thread to avoid freezing the UI.

Note

Detail views are initially empty. Detail data is loaded dynamically when a user expands a master row. The OptionsDetail.AllowExpandEmptyDetails property is set to true to allow users to expand master rows when details have no data.
