1、Button
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(); }
2、HyperlinkButton
<Grid Background="Transparent"> <StackPanel Margin="120 0 0 0"> <!-- HyperlinkButton - 带超链接的按钮 NavigateUri - 按钮要导航到的 Uri --> <HyperlinkButton Name="btnLink" Content="webabcd blog" FontSize="36" Foreground="Blue" NavigateUri="http://webabcd.cnblogs.com" /> </StackPanel> </Grid>
3、RadioButton

private void RadioButton_Click(object sender, RoutedEventArgs e) { if (a.IsChecked == true) answer.Text = a.Content.ToString(); else if (b.IsChecked == true) answer.Text = b.Content.ToString(); else if (c.IsChecked == true) answer.Text = c.Content.ToString(); else answer.Text = d.Content.ToString(); }
4、CheckBox
