How to restrict chip selection in Xamarin

1 min read

This article explains how to restrict the chip selection in Xamarin ChipGroup.

Consider if your requirement is to restrict a specific chip from the selection process, it can be achieved by controlling the selection functionality using the SelectionChanging event Cancel argument.

Note:

It restricts the chip selection when you set Cancel value to true.

Here, users are allowed to select all languages except Java.

XAML

<buttons:SfChipGroup 
    Type="Filter" 
    ItemsSource="{Binding Languages}"
    SelectedChipBackgroundColor="Red"
    ChipPadding="8,8,0,0"
    SelectionIndicatorColor="White"
    SelectionChanging="SfChipGroup_SelectionChanging"
    DisplayMemberPath="Name">
</buttons:SfChipGroup>

        private void SfChipGroup_SelectionChanging(object sender, Syncfusion.Buttons.XForms.SfChip.SelectionChangingEventArgs e)
        {
          if(e.AddedItem != null && (e.AddedItem as Language).Name.Equals("Java"))
            {
                e.Cancel = true;
            }
        }

public class ViewModel : INotifyPropertyChanged
    {
        private ObservableCollection<Language> languages;
        public ObservableCollection<Language> Languages
        {
            get
            {
                return languages;
            }
 
            set
            {
                languages = value;
                OnPropertyChanged("Languages");
            }
        }
 
        public ViewModel()
        {
            Languages = new ObservableCollection<Language>();
            Languages.Add(new Language () { Name = "C#" });
            Languages.Add(new Language () { Name = "HTML" });
            Languages.Add(new Language () { Name = "Java" });
            Languages.Add(new Language () { Name = "JS" });
        }
 
       ..
 
    }

Output
