强文本
public MainPage()
{
InitializeComponent();
// Sample code to localize the ApplicationBar
//BuildLocalizedApplicationBar();
Loaded += MainPage_Loaded;
}
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
webbrw.LoadCompleted += webbrw_LoadCompleted;
webbrw.Source = new Uri("http://www.youtube.com/user/tseries");
}
void webbrw_LoadCompleted(object sender, NavigationEventArgs e)
{
progressbar.IsIndeterminate = false;
}
推荐答案
如果您只是想在加载页面时显示栏并在之后隐藏它,您'重新使用错误的属性.IsIndeterminate
属性报告通用进程 (true) 或基于值 (false) 的进程.要隐藏您应该使用的进度条:
If you simply want to show the bar while loading the page and hide it afterwards, you're using the wrong property. The IsIndeterminate
property reports a generic process (true) or one based on a value (false). To hide the progressbar you should use:
progressbar.Visibility = Visibility.Collapsed;
