在WPF的Page控件中按F5会刷新控件，如有需要进行屏蔽，可使用附加属性实现：

public static class DisableNavigation
{
	public static bool GetDisable(DependencyObject o)
	{
		return (bool)o.GetValue(DisableProperty);
	}

	public static void SetDisable(DependencyObject o, bool value)
	{
		o.SetValue(DisableProperty, value);
	}

	public static readonly DependencyProperty DisableProperty =
		DependencyProperty.RegisterAttached("Disable", typeof(bool), typeof(DisableNavigation),
											new PropertyMetadata(false, DisableChanged));

	public static void DisableChanged(object sender, DependencyPropertyChangedEventArgs e)
	{
		var frame = (Frame)sender;
		frame.Navigating += DontNavigating;
		frame.NavigationUIVisibility = NavigationUIVisibility.Hidden;
	}

	private static void DontNavigating(object sender, NavigatingCancelEventArgs e)
	{
		if (e.NavigationMode == NavigationMode.Refresh)
			e.Cancel = true;
		else if (e.NavigationMode == NavigationMode.Back)
			e.Cancel = true;
	}
}

使用：

<Frame NavigationUIVisibility="Hidden"
       Source="{Binding MainModel.Url}"  
       beha:DisableNavigation.Disable="True"/>
