Alternative Color for Gridview Row in Xamarin Forms - styles

Question

I am trying to make alternative row color in Xamarin Gridview, unfortunately it is not working, can you anyone please see what mistake I am ding here.
I went through few articles and all they suggest to use converter to make alternative row color.
namespace CommonUI.Utilities
{
public class AlternatingHighlightColorConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
Color rowcolor = Color.Transparent;
if (value == null || parameter == null) return Color.White;
var index = ((ListView)parameter).ItemsSource.Cast<object>().ToList().IndexOf(value);
if (index % 2 == 0)
{
rowcolor = Color.Pink;
}
return rowcolor;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
}
