WebClient DownloadStringCompleted仅触发一次

Question

I got this code:

private void LoadXML()
{
    WebClient myWebClient = new WebClient();
    myWebClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(myWebClient_DownloadStringCompleted);
    myWebClient.DownloadStringAsync(new Uri(strXMLPath));

}

private void myWebClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    //Do stuff                       
}

myWebClient_DownloadStringCompleted is only fired first time I call LoadXML() . There is no errors on the xml file im trying to get, so I should be expecting a result. What am I missing?

Answer 1

I managed to narrow the problem down. I had the silverlight object inside an asp:updatepanel , when I moved the silverlight object outside the updatepanel, things started to work.
