7.在Read模式情况下，我们想要email地址和主页URL这两项显示成按钮。点击email地址这个按钮应该打开默认的email应用程序，点击主页URL的按钮应该在Frame_RightPane里显示主页的内容。我们创建两个URI，在按钮的事件处理函数里，只要简单地导航到这两个URI就可以了。我们在ContactDetailPage1.xaml.cs里修改代码：
private void NavigateToHome(object sender, RoutedEventArgs e)
{
if (this.txtHomePage != null)
{
NavigationService ns =
NavigationService.GetNavigationService(this);
ns.Navigate(new Uri(this.txtHomePage.Text));
}
}
private void SendEmail(object sender, RoutedEventArgs e)
{
if (this.txtEmailAddress != null)
{
NavigationService ns =
NavigationService.GetNavigationService(this);
ns.Navigate(new Uri("mailto:" + this.txtEmailAddress.Text));
}
}
{
if (this.txtHomePage != null)
{
NavigationService ns =
NavigationService.GetNavigationService(this);
ns.Navigate(new Uri(this.txtHomePage.Text));
}
}
private void SendEmail(object sender, RoutedEventArgs e)
{
if (this.txtEmailAddress != null)
{
NavigationService ns =
NavigationService.GetNavigationService(this);
ns.Navigate(new Uri("mailto:" + this.txtEmailAddress.Text));
}
}
8.像我们在第一个page function里做过的一样，我们创建第二个功能页ContactDetailPage2，设定类型参数为Object。这个页面由两个TextBox组成，一个显示家庭地址，另一个显示公司地址。另外还添加一个Cancel和一个Finish按钮。
