UI Thread will be freezed when you click startDownload(). If you don't want get form freezed, you use startDownload() in another thread and make progress updating in cross-threaded. One way, <pre><code>private void startDownload() { Thread thread = new Thread(() => { WebClient client = new WebClient(); client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged); client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted); client.DownloadFileAsync(new Uri("http://joshua-ferrara.com/luahelper/lua.syn"), @"C:\LUAHelper\Syntax Files\lua.syn"); }); thread.Start(); } void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e) { this.BeginInvoke((MethodInvoker) delegate { double bytesIn = double.Parse(e.BytesReceived.ToString()); double totalBytes = double.Parse(e.TotalBytesToReceive.ToString()); double percentage = bytesIn / totalBytes * 100; label2.Text = "Downloaded " + e.BytesReceived + " of " + e.TotalBytesToReceive; progressBar1.Value = int.Parse(Math.Truncate(percentage).ToString()); }); } void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e) { this.BeginInvoke((MethodInvoker) delegate { label2.Text = "Completed"; }); } </code></pre> Read more multi-threading in Google like this <a href="http://msdn.microsoft.com/en-us/library/ms951089.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/ms951089.aspx</a> -Fixed missing close ); to the bgThread declaration

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
