After you add the Enhanced Tab Control, edit the properties as desired, and click OK. Then, right-click on the Enhanced Tab Control and select "New Page". The page is what defines each tab properties.
Switching between pages/tabs of the tab controls is also possible by selecting a tab control then pressing [Ctrl+Page Up], [Ctrl+Page Down], and [Ctrl]+<Number> to move between pages/tabs.
When working with an Enhanced Tab Control object, it is important to realize that there are two specific areas to select when editing the properties for the control.
The first area is the "entire" tab control object, with the selection handlebars located around the whole control. To select the whole control, click in the area where the tabs are located. Right-clicking here will provide a list of properties for the entire tab control. (Properties, New Page, Next Page, etc.)
The second area is the actual tab page, which will contain other form controls. To select the page, click in the rectangle portion below the tabs. Right-clicking here will provide a list of properties for just the page.
Delete a Tab Page
To delete a tab page, the tab page must be displayed. Right click in the Tab Control area where the tabs are located, and select "Goto" to displayed the specific page. Then, select the page and press the [Delete] key. The page can also be deleted by right clicking on the tab page and selecting "Delete Page".
