We'll need some more information in order to simulate the issue. Could you please send us code inside AddingNewDataItem() and RowEditEnded() event handlers. Also we need some more details about data source and business object to which RadGridView is bound. A sample project that demonstrates the issue will be great.

Generally everything looks OK with your code. Indeed EntityCollection does not implement IList interface and RadGridView cannot add this item automatically, so you have to add it manually. But I cannot see any reason why there is a different behavior when RadGridView is empty and when there is item. Could you please send me a sample project that I can debug on my side?
