And the code behind

And the code behind

public void hlnkbtnminimize_Click(object sender, RoutedEventArgs e)
{
    var ctr = e.OriginalSource as HyperlinkButton;
    DependencyObject dep = (DependencyObject)e.OriginalSource;
    if (ctr != null)
    {
        Image objminImg = (Image)(ctr.FindName("imgminimize"));
        Image objmaxImg = (Image)(ctr.FindName("imgmaxmize"));
        TextBlock objAnswer = (TextBlock)(ctr.FindName("txtAnswer"));
        TextBlock objSerialNo = (TextBlock)(ctr.FindName("txtbAutogeneratedID"));
        objAutogeneratedSerialNo =Convert.ToInt32(objSerialNo.Text);
        int serialNo = (objAutogeneratedSerialNo) ;
        objchk=Convert.ToString(ctr.Tag);
        if (objminImg.Visibility == Visibility.Visible)
        {
            //  GVMarketList.RowHeight= 30;
                //  ctr.Height = 40;

                objminImg.Visibility = Visibility.Collapsed;
                objmaxImg.Visibility = Visibility.Visible;
