You need to write your custom skin in order to do that. Quest Web Parts use Telerik toolbar component and I need your QWP version so I can tell you exactly what is the Telerik version. Please go to About dialog of one of QWP web parts and check the version and also let me know the SharePoint version.
Basially, I’d like to show the title bar, but not use the default font and color. I’ve been through the ezEdit screens and taught myself to change css settings for the Grid, pager, headers etc., but I don’t see where to do the same for the title bar. Is it possible?
