Remarks

The visual representation of a Picker is similar to a Entry, but a picker control appears in place of a keyboard.

The following example shows the creation of a Picker.

using System;
using System.Collections.Generic;
using Microsoft.Maui.Controls;

namespace FormsGallery
{
    class PickerDemoPage : ContentPage
    {
