无法保存到表或数据库

Question

this.allDataTablesSuperDrive.TimeSheet.Rows.Add(rowCount, nameSelected, day, hour, null, null, null, null);

this.allDataTablesSuperDrive.TimeSheet.AcceptChanges();

我无法使用此代码进行保存，我刷新了数据网格和表，但没有任何显示。

我尝试使用更新和填充，但两者都返回错误，提示它们对此不可用。请帮助

编辑：我在运行代码时没有任何异常，唯一的问题是当我检查数据库或gridview是否已更新时，什么都没有改变。我尝试填写并更新，还刷新了其他表单，但是什么也没有出现。

还有allDataTablesSuperDrive，这是我使用的绑定源。
