DownloadStringCompleted event does not fire

Question

I am developing a windows phone application. The webclient does not fire as I expected. The related code is as below:

public PArticle(PocketListItem aPli)
    {
        this.pli = aPli;

        using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
        {
            if (!isf.FileExists(aPli.ID + ".json"))
            {
                WebClient client = new WebClient();
                client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
                client.DownloadStringAsync(new Uri(pli.Url));
            }
            else
            {
                string json = RetrieveDataFromLocalStorage(aPli.ID + ".json");

                PocketArticle pa = JsonConvert.DeserializeObject<PocketArticle>(json);
                this.text = pa.text;
            }
        }
    }

    void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        var readability = Readability.Create(e.Result);
        this.text = readability.Content;
    }

I know it's a synchronous/asynchronous problem. But I have no idea about how to handle it.

Thanks in advance.

Code seems to be fine, check whether your Url is valid or not? — nkchandra, Jun 14 '12 at 09:09

I have tested the WebClient part of your code with 2 different URLs http://riktamtech.com and http://google.com. In both cases, the DownloadStringCompleted event is raised. I observed it by placing a break point.

So I suggest you to test again with break points.
