Cannot Change The Color of Disabled SFNumericUpDown

i have created a custom SFNumericUpDown with a bindable proprety called DisabledColor

       public Color DisabledColor
        {
            get { return (Color)GetValue(DisabledColorProperty); }
            set { SetValue(DisabledColorProperty, value); if (!IsEnabled) TextColor = value; }
        }
public static readonly BindableProperty DisabledColorProperty = BindableProperty.Create(
                                                        nameof(DisabledColor),
                                                        returnType: typeof(Color),
                                                        declaringType: typeof(MyNumericUpDown),
                                                        defaultValue: Color.Black,
                                                        defaultBindingMode: BindingMode.TwoWay);


and in my android render 


[assembly: ExportRenderer(typeof(MyNumericUpDown), typeof(MyNumericUpDownRender))]
namespace Comodor.Droid.CustomConttrols
{
    class MyNumericUpDownRender: SfNumericUpDownRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<SfNumericUpDown> e)
        {
            base.OnElementChanged(e);
            if (Control != null)
            {
                var dp = (MyNumericUpDown)Element;
                if (!dp.IsEnabled)
                {
                    Control.TextColor = dp.DisabledColor.ToAndroid();
                }
            }
        }
        protected override void OnElementPropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
        {
            base.OnElementPropertyChanged(sender, e);
            if (e.PropertyName.Equals("IsEnabled"))
            {
                var dp = (MyNumericUpDown)Element;
                if (!dp.IsEnabled)
                {
                    Control.TextColor = dp.DisabledColor.ToAndroid();
                }
                else
                {
                    Control.TextColor=dp.TextColor.ToAndroid();
                }
            }
        }
    }

Hi Mohamed, 
 
Greetings from Syncfusion. 
 
We have prepared the sample based on your provided code snippet. TextColor is updated properly based on IsEnabled property. Can you please check with the sample in the following location?
