Hi Team,

Thanks for the update.

We can resolve the reported issue by setting Mode as TwoWay as like below code snippet.

XAML:

 

  <syncfusion:SfPicker 

            x:Name="picker" 

            HeaderText="Select a Color" 

            IsOpen="{Binding IsOpenColor,Mode=TwoWay}" 

            ItemsSource="{Binding Colors}" 

            PickerMode="Dialog" 

            ShowFooter="True" /> 

Please let us know if you have any other queries.

Hi Team,

Thanks for the update.

We can achieve your requirement by using Localization as like below code snippet.

C#: 

        public MainPage() 

        { 

            InitializeComponent(); 

            On<Xamarin.Forms.PlatformConfiguration.iOS>().SetUseSafeArea(true); 

            DependencyService.Get<ILocalize>().SetLocale("zh-CN"); 

 

            PickerResourceManager.Manager = 

                         new ResourceManager("PickerLocalization.Resources.Syncfusion.SfPicker.XForms", GetType().GetTypeInfo().Assembly); 

        } 

Android: 

[assembly: Xamarin.Forms.Dependency(typeof(PickerLocalization.Droid.LocalizationService))]

namespace PickerLocalization.Droid 

{    public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity 

    { 

… 

    } 

    public class LocalizationService : ILocalize 

    { 

        public void SetLocale(string language) 

        { 

            var userSelectedCulture = new CultureInfo(language); 

            Thread.CurrentThread.CurrentUICulture = userSelectedCulture; 

        } 

    } 

}
