SFAutoComplete custom renderer problem after update from 17.0.2.51 to 17.0.3.14

Hello,

I have SfAutoComplete custom Android renderer. 

[assembly: ExportRenderer(typeof(CustomSfAutoComplete), typeof(AutoComplete_Renderer))]

namespace TipCalculator.Droid.Renderers
{
    public class AutoComplete_Renderer : SfAutoCompleteRenderer
    {

        protected override void OnElementChanged(ElementChangedEventArgs<SfAutoComplete> e)
        {
            base.OnElementChanged(e);
            if (Control != null)
            {
                Control.GetAutoEditText().ImeOptions = Android.Views.InputMethods.ImeAction.Done;
                Control.InputType = Android.Text.InputTypes.TextFlagCapWords;
            }
        }

    }
}

it works fine in 17.0.2.51, but after update to 17.0.3.4 I had to add additional constructors:

        public AutoComplete_Renderer(Context context) : base(context)
        {
        }

        public AutoComplete_Renderer(Context context, IVisual visual) : base(context, visual)
        {
        }

but now it throws exception during page OnSizeAllocated

System.MissingMethodException: 'Constructor on type 'TipCalculator.Droid.Renderers.AutoComplete_Renderer' not found.'

Could you advise me a correct custom renderer code for the latest version?

Best regards,
Radek

Hi Radoslaw,

Greetings from Syncfusion. 
 
Query: Could you advise me a correct custom renderer code for the latest version? 
 
We glad to inform that Material UI design has been implemented for our Syncfusion control with latest version (Volume 3 2019 release). Hence we have updated the way to use the custom renderer of Syncfusion SfAutoComplete in below and also update the sample here

Sample Link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/CustomRenderer-268199443

Code Snippet: 
 
[assembly: ExportRenderer(typeof(CustomClass), typeof(CustomRendererAndroid))]

 
[assembly: ExportRenderer(typeof(CustomClass), typeof(MaterialSfAutoCompleteRenderer), new[] { typeof(VisualMarker.MaterialVisual) })] 
namespace CustomRenderer.Droid 
{ 
    public class CustomRendererAndroid : SfAutoCompleteRenderer 
    { 
        public CustomRendererAndroid(Context context) : base(context) 
        { 
        } 
 
        public CustomRendererAndroid(Context context, IVisual visual) : base(context, visual) 
        { 
        } 
 
        protected override void OnElementChanged(ElementChangedEventArgs<Syncfusion.SfAutoComplete.XForms.SfAutoComplete> e) 
        { 
            base.OnElementChanged(e); 
            if (Control != null) 
            { 
                Control.GetAutoEditText().ImeOptions = Android.Views.InputMethods.ImeAction.Done; 
                Control.InputType = Android.Text.InputTypes.TextFlagCapWords; 
            } 
        } 
    } 
 
    internal class MaterialSfAutoCompleteRenderer : SfAutoCompleteRenderer 
    { 
        public MaterialSfAutoCompleteRenderer(Context context) : base(context, VisualMarker.Material) 
        { 
        } 
    } 
} 
  
Please check with the sample and let us know if you have any concern.

Regards,
Hemalatha M.
