Answer 1

Xamarin Forms does include a combo box control, it just isn't called a combo box. XF calls it a Picker. It's pretty easy to use and includes properties you can bind to for ItemSource and SelectedItem/SelectedIndex.

Answer 2

You can use Picker control at xamarin to achieve list some objects in a box. I recommend you to follow the MVVM pattern to bind datasource and handle events. There is code samples for it that created by Microsoft.

But basically you have to add a Picker to your xaml:

<StackLayout Margin="20">
        <Label Text="Bindable Picker Demo" FontAttributes="Bold" HorizontalOptions="Center" />
        <Picker Title="Select a country" ItemsSource="{Binding CountryList}" SelectedItem="{Binding SelectedColorName, Mode=TwoWay}" />
        
    </StackLayout>

And in your model just set your Countrylist property and It is selected item.

public IList<string> CountryList
    {
        get
        {
            return new List<string> {"USA","Germany","England"};
        }
    }

If you want to make search in your Picker you have to create your own control. According your wishes an Entry and a Listview may be enough. You have to update your list in TextChanged event of Entry.

Answer 3

You can create your own ListView with ItemsSource as a country list, and SearchView with TextChanged method, where you change your ItemsSource by search value (and firstly, ItemsSource would be empty, because of empty search filter).

Also you can check this link, that could be also useful.

UPDATE:

If you need a searchable Picker, there is a github project, that you can use. It has a search. Link to project.
