    <p>I have an application where I am uploading a file in blocks. My front end is WPF and I have a progress bar to show file upload progress (upload is done by separate thread, and the progress bar is in a separate form invoked by the child thread when uploading starts).</p> <p>I found the total number of blocks in the file to set the maximum property of the progress bar.</p> <p>Now for each block uploaded I increment the value of progress bar by 1.</p> <p>But to my surprise, the progress bar starts to increment but never completes ( it stops showing progress after few blocks ).</p> <p>Here is code for the thread responsible for uploading files:</p> <pre> System.Threading.Thread thread = new Thread( new ThreadStart( delegate() { // show progress bar - Progress is the name of window containing progress bar Progress win = new Progress(); win.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterScreen; win.Show(); // find number of blocks long BlockSize = 4096; FileInfo fileInf = new FileInfo(filename); long FileSize = fileInf.Length; long NumBlocks = FileSize / BlockSize; //set the min and max for progress bar win.Dispatcher.Invoke( new Action( delegate() { win.progressBar1.Minimum = 0; win.progressBar1.Maximum = NumBlocks; } ), System.Windows.Threading.DispatcherPriority.Render); //upload file while (true) { // code to upload the file win.Dispatcher.Invoke( new Action( delegate() { win.progressBar1.Value += 1; } ), System.Windows.Threading.DispatcherPriority.Render); } } </pre> <p>Can someone help me analyze why is this happening.</p> <p>Thanks.</p>

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.
