老师，表属性Datacolchanged 中的以下黄色可以帮忙纠下一下吗？ 提示 列名 \'true\' 无效。

If  e.DataCol.Name = "PartNo" Then
        If e.DataRow.IsNull("PartNo") Then
            e.DataRow("Priority") = True
e.DataRow("FUsed") = False

        Else
            Dim brrr As DataRow = e.DataRow
            Dim cmd As new SQLCommand
            cmd.CommandText = "Se lect * From {t_SupplyEntry} Where FItemID = \'" & brrr("FItemID") & "\'and FPrioritized = true "
            cmd.C
            Dim Values = cmd.ExecuteValues
            If Values.Count > 0 Then
                brrr("Priority") = False
brrr("FUsed") = False

            Else
                brrr("Priority") = True
brrr("FUsed") = False

            End If
        End If
End If
