在VS2012项目中,如果添加或修改相应的行状态,我喜欢将记录数据字段(DateTimeStamp)设置为当前系统日期时间。为此,我使用以下代码:

Private Sub LicenceCheckBindingNavigatorSaveItem_Click(sender As Object, e As EventArgs) Handles LicenceCheckBindingNavigatorSaveItem.Click
    Me.Validate()
    Dim dt As DataTable = EfaDesktopDataSet.Tables("LicenceCheck").GetChanges
    If Not IsNothing(dt) Then
        For Each dr As DataRow In dt.Rows
            If dr.RowState <> DataRowState.Unchanged And dr.RowState <> DataRowState.Deleted Then
                dr.BeginEdit()
                dr.Item("DateTimeStamp") = Date.Now
                dr.EndEdit()
            End If
        Next
    Else
        Dim dr As DataRow = LicenceCheckBindingSource.Current.row
        If dr.RowState = DataRowState.Unchanged Then
            If isDataChanged(dr, "RuleTitle") Then

            End If
        End If
    End If
    Me.LicenceCheckBindingSource.EndEdit()
    Me.LicenceCheckTableAdapter.Update(Me.EfaDesktopDataSet.LicenceCheck)
End Sub

在DEBUG步骤中,我认识到Date已转移到数据列,但在更新并重新请求记录之后,该列不包含数据。

任何想法为什么?
