How to add Picker data in Xamarin Forms

Question

Is it possible to add additional data to a Picker that already contains data?

Hello,

You can do this by adding itemsource in the background code.

For example, you have Picker in the layout and add button for testing.

<Button Text="click" Clicked="Button_Clicked" ></Button>
<Picker x:Name="MyPicker"></Picker>

Then you can set itemsource in the background code and add additional data to a Picker that already contains data.

I use ObservableCollection to contains data, when you add data in it, it will update at the runtime.

public partial class MainPage : ContentPage
    {
        ObservableCollection<string> strings;
       public MainPage()
        {
            InitializeComponent();
            strings = new ObservableCollection<string>();
            for (int i = 0; i < 10; i++)
            {
                strings.Add(i.ToString());
            }
            MyPicker.ItemsSource = strings;
        }
        private void Button_Clicked(object sender, EventArgs e)
        {
            strings.Add("1234");
        }
    }
