Private Sub xdg_ImpForecast_SearchList_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Input.MouseButtonEventArgs) Handles Fxdg_ImpForecast_SearchList.MouseDoubleClick

Fgrid_bjDetail.DataContext = CType(xdg_ImpForecast_DetailList.ActiveRecord, DataRecord).DataItem

    End Sub

...

    Private Sub D_Fxte_Remark_TextChanged(ByVal sender As Object, ByVal e As System.Windows.RoutedPropertyChangedEventArgs(Of String)) Handles D_Fxte_Remark.TextChanged
'''''''can get cell value

  Debug.Print(Now.ToString & "---" & Fxdg_ImpForecast_detailList.GetCellValue("REMARK") & "---")
