Tab
The Tab control adds a tab to the dialog. Any of the other controls can be added to the new tab. The Tab control has the following properties:
Identifier. The unique identifier for the control.
Title. The title of the tab.
Position. Specifies the position of the tab on the dialog, relative to the other tabs on the dialog.
Enabling Rule. Specifies a rule that determines when the current control is enabled. Click the ellipsis (...) button to open the Enabling Rule dialog box and specify the rule. The Enabling Rule property is visible only when other controls that can be used to specify an enabling rule exist on the canvas.
Note: The Tab control is not available in compatibility mode.
