RadProgressBar is designed to display progress information to the user during a long-running operation.
In addition to using the Telerik Presentation Framework for theming, it offers other advantages over the standard Windows Forms ProgressBar control:
Support for displaying text and images within the body of the progress bar.
Dashed and cross-hatched indicator styles.
Support for displaying two values on a single progress bar. The second value is indicated by a change in shade in the unfilled portion of
the progress bar.
