WPF: Real time timeline control needed

I need to reflect progress of execution of numerous tasks in real time.

I wondering is it any WPF\Silverlight control which do this.

Here what I found, but this controls don't meet my needs:

If you are looking for a progress bar that updates in real time, I don't know of any 3rd party controls, but you can update a standard ProgressBar control based on work being done on a background thread using the WPF Dispatcher. I have implemented this pattern with multiple threads reporting back to multiple progress bars in a tree view simultaneously with no problems.

Here are a few articles I found that walk through this approach:

• "WPF Multithreading Using the Background Worker and Reporting the Progress to the UI" (ElegantCode.com)
• "Simple WPF Progress Window with Cancellation" (blog.quantumbitdesigns.com)
