Hello Rama Krishna,
In order for you to be able to Edit control properties, the control has to be part of the CMS. Now, when working with templates there are two cases:
- Including the controls directly in the masterpage (what you did)
- Including the controls in the CMS template (from within the CMS, the template uses the masterpage, but is not identical to it
You would have to use the second apporach in this case, and this is what Jeff suggested in his previous reply to you. If you only include a ContentPlaceHolder in the masterpage, then go to Pages -> Templates
and edit the template using the respective masterpage, you will be able to drop a RadTabStrip directly from the Sitefinity toolbox. After that you'll be able to edit the properties of RadTabStrip with the Sitefinity property editor.
Here's an article discussing the use of templates, what you need is in the second paragraph:
