Before you call Delete(), you should also remove it from the datasource for the grid.  Once delete is called, the entity will be in a detached state and should not have any operations performed on it.  As Mark points out, SaveChangesAsync() will then finally commit the delete to the database.

STUDENT stud = Students.Where(t => t.ID == Convert.ToDecimal(_id)).Single();
stud.EntityAspect.Delete();
_mgr.SaveChangesAsync();

That should do everything you need... stud is not coming back as a null entity, correct?

You need to call stud.EntityAspect.Delete(); rather than _mgr.RemoveEntity]]> Wed, 18 Aug 2010 14:25:32 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=2073&PID=8093#8093 http://www.ideablade.com/forum/forum_posts.asp?TID=2073&PID=8091#8091 Author: bala
