块参照与PropertyGrid的绑定问题

davehuhudave

我把某一块参照与PropertyGrid进行了绑定，但是修改PropertyGrid属性时候就出错并提示为非写状态，但是我明明给这个块参照写操作Enable了，望版主指教

               Dim lock As DocumentLock = AcadApp.DocumentManager.MdiActiveDocument.LockDocument()
                Using trans As Transaction = db.TransactionManager.StartTransaction()
                    Dim brf2 As AttributeReference = trans.GetObject(id, OpenMode.ForWrite)
                    Me.PropertyGrid1.SelectedObject = brf2
                End Using
                lock.Dispose()
