Change dynamically the SfSegmentedControl.ItemsSourceProperty

[Carlos]

Hello,

I have a SfSegmentedControl with three segments and I'd like to know how to change the SfSegmentedControl.ItemsSourceProperty when a Clicked button event is triggered?

I'm not using XAML, just C#.

Thanks,

Hi Carlos, 

  

Greetings from Syncfusion. 

  

We have checked your requirement and it looks like modifying the entire ItemsSource of SfSegmentedControl by adding new items or removing the existing item or replace the existing ItemsSource with new one. Based on your request, we have prepared a sample with the supported item in ItemsSource with using the ObservableCollection. Please download the same in below link

Code Snippet [C#]: 

  

public partial class MainPage : ContentPage 

    { 

        SfSegmentedControl stringSegmentControl; 

  

        SfSegmentedControl segmentControl; 

  

        public MainPage() 

        { 

            InitializeComponent(); 

  

            StackLayout stackLayout = new StackLayout(); 

  

            stringSegmentControl = new SfSegmentedControl() 

            { 

                ItemsSource = new ObservableCollection<string>() { "Segment 1", "Segment 2", "Segment 3" }, 

                Margin = new Thickness(0, 40, 0, 0) 

            }; 

  

            segmentControl = new SfSegmentedControl() 

            { 

                ItemsSource = new ObservableCollection<SfSegmentItem>() 

                { 

                    new SfSegmentItem(){Text = "Segment 1"}, 

                    new SfSegmentItem(){Text = "Segment 2"}, 

                    new SfSegmentItem(){Text = "Segment 3"}, 

                }, 

                Margin = new Thickness(0, 40, 0, 0) 

            }; 

  

            Button dynamicUpdate = new Button() { Text = "Click to Update" }; 

            dynamicUpdate.Clicked += DynamicUpdate_Clicked; 

  

            stackLayout.Children.Add(stringSegmentControl); 

            stackLayout.Children.Add(segmentControl); 

            stackLayout.Children.Add(dynamicUpdate); 

  

            this.Content = stackLayout; 

            

        } 

  

        private void DynamicUpdate_Clicked(object sender, EventArgs e) 

        { 

            var stringCollection = (stringSegmentControl.ItemsSource as ObservableCollection<string>); 

            stringCollection.Add("Segment " + (stringCollection.Count + 1).ToString()); 

  

            var segmentCollection = (segmentControl.ItemsSource as ObservableCollection<SfSegmentItem>); 

            segmentCollection.Add(new SfSegmentItem() { Text = "Segment " + (segmentCollection.Count + 1).ToString() }); 

  

        } 

    }
