我正在Windows Phone上开发一个应用程序,其中7.1版本设置为我的目标版本。我遇到的问题是我的页面上的一个列表视图拒绝显示。
我已经调试过以确保列表中的内容被解析。当我使用Windows 8模拟器时,应用程序运行正常。但是,在应用程序的其他页面中填充其他列表视图时使用的相同技术可以在此单页面中显示的所有模拟器上正常工作。
我甚至尝试设置绑定堆栈面板的颜色,看它是否会显示,但它没有任何内容。 我真的很困惑,我的代码非常完美。我想知道在使用Windows Phone模拟器之前是否有任何人出现这个问题?
private void countdownClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
HtmlDocument doc = new HtmlDocument();
if (e.Error != null)
{
//MessageBox.Show(e.Error.InnerException.Message + "\n Ensure You Have A Working Internet Connection");
return;
}
doc.LoadHtml(e.Result);
String noCountdown = "<div><span>Sorry no buses are expected within 30 minutes of this stop. Please try again later or go to www.tfl.gov.uk</span></div>";
if (e.Result.Contains(noCountdown))
{
//No Buses Expected;
return;
}

{
HtmlNode stopCountdownNode;

尝试设置用于绑定到public的类访问说明符并尝试一下。如果有效,请告诉我。
例如:
public class Bindingclass
{
public string Name{get;set;}
}
