1. Navigation

在 Page 中：

this.Frame.Navigate(typeof(MainPage));

其他：

Frame frame = Window.Current.Content as Frame;
frame.Navigate(typeof(MainPage));

在页面之间传递信息：

page1.xaml.cs

private void HyperlinkButton_Click(object sender, RoutedEventArgs e){    this.Frame.Navigate(typeof(page2), tb1.Text);}

page2.xaml.cs

private void navigationHelper_LoadState(object sender, LoadStateEventArgs e){    string name = e.NavigationParameter as string;    if (!string.IsNullOrWhiteSpace(name))    {        tb1.Text = "Hello, " + name;    }    else    {        tb1.Text = "Name is required.  Go back and enter a name.";    }}

2.用c# 设置 button的 color

button.Background = new SolidColorBrush(Colors.Yellow);

namespace of color : Windows.UI

自定义 SolodColorBrush:

SolidColorBrush greenBrush = new SolidColorBrush(Colors.Green);

SolidColorBrush myBrush = new SolidColorBrush(Color.FromArgb(255, 20, 20, 90));

3. SearchBox

<SearchBox x:Name="mySearchBox"     FocusOnKeyboardInput="True"    QuerySubmitted="mySearchBox_QuerySubmitted"    Height="35"  />

private void mySearchBox_QuerySubmitted(SearchBox sender, SearchBoxQuerySubmittedEventArgs args){    this.Frame.Navigate(typeof(SearchResultsPage1), args.QueryText);}

4. Handle Back Button

如果用手机自带的返回键，需要在app.xaml.cs 中处理 BackPressedEvent

private void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e){    Frame frame = Window.Current.Content as Frame;    if (frame == null)    {        return;    }    if (frame.CanGoBack)    {        frame.GoBack();        e.Handled = true;    }}

如果用app中的返回键：

则自定义button的点击事件：

 private void Back_Click(object sender, RoutedEventArgs e)        {            Frame frame = Window.Current.Content as Frame;            if (frame == null)            {                return;            }            if (frame.CanGoBack)            {                frame.GoBack();            }        }

5. WebView

xaml:

<WebView Name="webView1" Width="1000" Height="800"/>

c#:

 protected override void OnNavigatedTo(NavigationEventArgs e)        {            Uri targetUri = new Uri(@"http://www.bing.com/");            webView.Navigate(targetUri);        }
