重新想象 Windows 8 Store Apps (2) - 控件之按钮控件: Button, HyperlinkButton, RepeatButton, ToggleButton, RadioButton, CheckBox, ToggleSwitch

作者：webabcd

介绍

重新想象 Windows 8 Store Apps 之按钮控件

  • Button - 按钮控件
  • HyperlinkButton - 超链按钮
  • RepeatButton - 按住后会重复执行单击操作的按钮
  • ToggleButton - 可切换状态的按钮
  • RadioButton - 单选框控件
  • CheckBox - 复选框控件
  • ToggleSwitch - 状态切换控件

示例
1、Button 的 Demo
ButtonDemo.xaml.cs

/*

 * Button - 按钮控件

 */

using System;

using Windows.UI.Popups;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Navigation;

namespace XamlDemo.Controls

{

    public sealed partial class ButtonDemo : Page

    {

        public ButtonDemo()

        {

            this.InitializeComponent();

        }

        protected override void OnNavigatedTo

(NavigationEventArgs e)

        {

            /*

             * Button - 按钮控件，其全部功能是通过其基类 ButtonBase 提供的

             *     ClickMode - 引发 Click 事件的模式：ClickMode.Release（默认值）, ClickMode.Press, ClickMode.Hover

             *     IsPointerOver - 设备指针（鼠标或手指等）是否在按钮上

             *     IsPressed - 当前按钮是否处于按下的状态

             *     Command 和 CommandParameter 等写到 MVVM 的时候再详细写

             */

            Button btn = new Button();

            btn.Content = "我是按钮";

            btn.ClickMode = ClickMode.Hover;

            btn.Click += btn_Click;

            root.Children.Add(btn);

        }

        async void btn_Click(object sender, 

RoutedEventArgs e)

        {

            await new MessageDialog("触发了按钮的 

Click 事件").ShowAsync();

        }

    }

}
