In the Outlook Bar "firstlook" demo example they use the "storyboard" for the main content view area of the telerik webmail. Was trying to change that demo so that we can use the RadPage Navigation instead of the story board. Found out there are issues, the project compiles and everything runs as normal but the page you try to navigate to never shows up in the main content area (the area you set with the RadFrameContainer). So probably a bug in telerik in which Outlook Bar cannot be used in combination with RadPage Navigation??? Sent a support ticket to telerik support together with a sample project. Will update with their response.
