If you mean In-Line Edit like once you select the data and begin to edit it, the database receives the processed data, then I am not sure. If you mean In-Line edit like edit the data on the grid then hit a submit button and that processes all the changes, then I can say yes it does. While the first case might be possible with some Ajax component to it, I would not know since that was not my use case so I cannot say for sure.
