I wish you the best of luck - bosses always love the UI pretty bits!
You can add new tabs by either of the following actions:
- Right click the Tab Container that you dropped on the page - click 'add tab panel'
- Click the tab container, then click the little arrow that appears near the top left. This gives you a context sensitive task list to add a panel. This is a much overlooked feature that is included on pretty much every control in Design mode!
If you can, I would recommend that you dive into the Source mode and look at the every now and again, so that you can get a handle of what the Drag/Drop interface is doing. I find that hand-coding as opposed to drag/drop gives me much more control over my code, and is much more satisfying!
The video from Joe was an older version of the toolkit, I can only assume that the Tollbox item was removed to stop people just dropping Tab Panels on the page without a container!
Have fun,
Steve
