hello to all 
how can I integrate the radwebbrwserbase in radtabstrip and created index tabitems and webbrowsers

Hello david,

Thank you for your question. I hope that your trial period is going fine. RadWebBrowserBase is used specifically in our RadRotator control. Please use our RadTabStrip and the standard WebBrowser control. I did not completely understand your question about index tabitems, so please provide me with additional information about your requirement.

All the best,
Nick
