Behind the scene we need to update any changes made in the property grid, in a SQL Server database, too. With our current implementation we fire a database request if a property is edited in the property grid. This is fine if only one entity has been selected. If more than one entity has been selected (ProperytSetMode “Intersection”) a database request is fired for each entity if a property is edited. This is not very performant for us. We need an event like “EditEnded” to figure out when the PropertySetViewModel has updated all ViewModels. Then we are able to updated the necessary changes in the database in a single call.
