SYMPTOMS
When you place a tab control on any page of another tab control, and then view the form in Form view, the embedded tab control is visible from any page of the main tab control.



RESOLUTION
The following example demonstrates how to use an event procedure that sets the Visible property of the embedded tab control to True only when a particular page has been selected.

 Follow steps 1 through 10 in the "Steps to Reproduce Behavior" section later in this article. Open the form in Design view. In the Object list (the drop-down list on the far left of the Formatting toolbar), click TabControlMain. Right-click TabControlMain, and then click Properties. Click the Event tab, and then click the OnChange property box. Click the Build button (...) to the right of the OnChange property box.</li> In the Choose Builder dialog box, click Code Builder, and then click OK.</li>  Set the OnChange property to the following event procedure:

Private Sub TabControlMain_Change If TabControlMain.Value = 1 Then TabControlEmbedded.Visible = True Else TabControlEmbedded.Visible = False End If      End Sub </li> On the View menu, click Form view.</li> Click Page 1 of TabControlMain, and then click Page 2. Note that TabControlEmbedded is visible only on Page 2.</li></ol>

NOTE: The Value property of a tab control contains the index number of the current Page object. There is one Page object for each tab in a tab control. The first Page object always has an index number of 0, the second has an index number of 1, and so on.
