Custom Renderer not fireing in Xamarin Forms (Android)

I am trying to remove the underline in the Syncfusion Autocomplete plugin ( or atleast make it transparent), this is my code:

    [assembly: ExportRenderer(typeof(SfAutoComplete), typeof(AutoCompleteRenderer))]
   namespace Pets.Droid
{
    public class AutoCompleteRenderer : SfAutoCompleteRenderer
    {

        protected override void OnElementChanged(ElementChangedEventArgs<SfAutoComplete> e)
        {
            base.OnElementChanged(e);
            if (Control != null)
            {
                GradientDrawable gd = new GradientDrawable();
                gd.SetStroke(0, Android.Graphics.Color.Transparent);
                Control.SetBackground(gd);
            }
        }
    }
}

but for some reason it wont fire, I also tried to create a custom MyAutoComplete class that inherits from SfAutoComplete and change the input in my XAML to local:MyAutoComplete but same results.

Anyone see what could be the issue?

Hi Chris,

Greetings from Syncfusion support.

We suggest you to use ShowBorder property to enable/disable the border in SfAutoComplete. We have created the sample for your reference. Please download it from the below link.

Sample link:  http://www.syncfusion.com/downloads/support/forum/143274/ze/AutoComplete_1146430840 

Please try our sample and let us know if you have any concern on this.

Thank you, I had no idea that line had to do anything with border, I would have called it an underline or similar. But, thank you, it works as intended now
