The control should be more customized than normal status bar control for WPF.

The XAML team has recently reviewed this issue and will not be addressing it as with Q1 2014 we introduced theme support for the System.Windows.StatusBar component. This means that you can use the native component within a Telerik powered application and at the same time have a seamless look and feel.  

You can check our Theming SDK demo under MSControls by downloading our SDK browser for WPF on the following page: http://demos.telerik.com/xaml-sdkbrowser/

If you want to share additional requirements about this control please contact us through the support ticketing system with details and a reference to this item.
