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

3、RadioButton

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

5、progressBar

public MainPage()
{
this.InitializeComponent();
progressBar1.Visibility = Visibility.Collapsed;
} private void begin_Click(object sender, RoutedEventArgs e)
{
progressBar1.Visibility = Visibility.Visible; if (radioButton1.IsChecked == true)
{
progressBar1.IsIndeterminate = false;
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromSeconds();
timer.Tick += timer_Tick;
timer.Start();
}
else
{
progressBar1.Value = ;
progressBar1.IsIndeterminate = true; }
}
async void timer_Tick(object sender, object e)
{
if (progressBar1.Value<)
{
progressBar1.Value += ;
}
else
{
(sender as DispatcherTimer).Tick -= timer_Tick;
(sender as DispatcherTimer).Stop();
await new MessageDialog("进度完成").ShowAsync();
} }
private void cancel_Click(object sender, RoutedEventArgs e)
{
progressBar1.Visibility = Visibility.Collapsed;
}

6、ScrollViewer

滚动的图片

private DispatcherTimer tmrDown;
private DispatcherTimer tmrUp;
public MainPage()
{
InitializeComponent();
for (int i = ; i <= ; i++)
{
Image imgItem = new Image();
imgItem.Width = ;
imgItem.Height = ;
if (i % == )
{
imgItem.Source = (new BitmapImage(new Uri("ms-appx:///a.jpg", UriKind.RelativeOrAbsolute)));
}
else if (i % == )
{
imgItem.Source = (new BitmapImage(new Uri("ms-appx:///b.jpg", UriKind.RelativeOrAbsolute))); }
else if (i % == )
{
imgItem.Source = (new BitmapImage(new Uri("ms-appx:///c.jpg", UriKind.RelativeOrAbsolute))); }
else
{
imgItem.Source = (new BitmapImage(new Uri("ms-appx:///d.jpg", UriKind.RelativeOrAbsolute))); }
this.stkpnlImage.Children.Add(imgItem);
} tmrDown = new DispatcherTimer();
tmrDown.Interval = new TimeSpan();
tmrDown.Tick += tmrDown_Tick;
tmrUp = new DispatcherTimer();
tmrUp.Interval = new TimeSpan();
tmrUp.Tick += tmrUp_Tick;
} void tmrUp_Tick(object sender, object e)
{
//scrollViewer1.ScrollToVerticalOffset(scrollViewer1.VerticalOffset - 10);
scrollViewer1.ChangeView(null, scrollViewer1.VerticalOffset - , null);
} void tmrDown_Tick(object sender, object e)
{
tmrUp.Stop();
// scrollViewer1.ScrollToVerticalOffset(scrollViewer1.VerticalOffset + 10);
scrollViewer1.ChangeView(null, scrollViewer1.VerticalOffset + , null);
} private void btnUp_Click(object sender, RoutedEventArgs e)
{
tmrDown.Stop();
tmrUp.Start();
} private void btnDown_Click(object sender, RoutedEventArgs e)
{
tmrDown.Start();
} private void stop_Click(object sender, RoutedEventArgs e)
{
tmrUp.Stop();
tmrDown.Stop();
}

7、Slider

Slider

public MainPage()
{
InitializeComponent();
redSlider.Value = ;
greenSlider.Value = ;
blueSlider.Value = ;
} void OnSliderValueChanged(object sender, RangeBaseValueChangedEventArgs e)
{ Color clr = Color.FromArgb(, (byte)redSlider.Value,
(byte)greenSlider.Value,
(byte)blueSlider.Value);
ellipse1.Fill = new SolidColorBrush(clr);
textBlock1.Text = clr.ToString();
redText.Text = clr.R.ToString("X2");
greenText.Text = clr.G.ToString("X2");
blueText.Text = clr.B.ToString("X2"); }
