Body
Here's the issue: <blockquote> upload is done by separate thread, and the progress bar is in a separate form invoked by the child thread when uploading starts </blockquote> If that means your child thread created the form, then that's the problem. Your child thread might be updating the progress bar values, but this will just invalidate the display, and not necessarily refresh the display. When a control's display is invalidated, it simply records that it must redraw it's display the next time it gets a chance. A refresh is when the control actually gets to render to the screen. A better approach is to create the progress bar form in the main thread. Your worker thread can then update the status, and your main thread will refresh the display. One thing to remember: if you're updating a control that was created in a different thread, you must do so via the control's dispatcher. <pre><code>var dispatcher = progressBar.Dispatcher; dispatcher.BeginInvoke(new Action( () => { progressBar.Value = currentProgress })); </code></pre> <hr /> Edit after seeing the code All you need to do is move the creation of the progress variable so that it is instantiated by the main thread before the worker thread is created. <hr /> <pre><code>Progress win = new Progress(); win.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterScreen; win.Show(); System.Threading.Thread thread = new Thread( new ThreadStart( delegate() { // ... </code></pre>

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.
