两个GridView：viewBarcodeSpecimens，viewBarcodePatient，隐藏viewBarcodeSpecimens的VertScrollVisbility = Never
激活viewBarcodePatient的事件TopRowChanged，原理是同步两个Grid的的TopRowIndex位置即可。
private void viewBarcodePatient_TopRowChanged(object sender, EventArgs e)
{
viewBarcodeSpecimens.TopRowIndex = (sender as GridView).TopRowIndex;
}
