ACC97: Disabled Tab Control Page Remains Visible

ID: Q161011

The information in this article applies to:

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

When the Enabled property of a page on a tab control is set to False, you can still click the tab and see its controls and the data they contain. However, you cannot change any of the data.


RESOLUTION

There are two methods you can use to hide the data on a disabled tab control page.

Method 1

Set the Visible property of the tab control page to False in the Load event of the form. This makes the tab control page and its tab invisible. Add the following procedure to the Load event of the form, substituting the name of your own tab control: 

   Private Sub Form_Load()
      If Me!TabCtl0.Pages(1).Enabled = False Then
         Me!TabCtl0.Pages(1).Visible = False
      End If
   End Sub

Method 2

Set the Visible properties of the controls on the tab control page to False in the Load event of the form. This hides the controls on that page, but allows the tab to remain visible. Add the following procedure to the Load event of the form, substituting the name of your own tab control and page controls: 

   Private Sub Form_Load()
     If Me!Tabctl0.Pages(1).Enabled = False Then
        Me!TabCtl0.Pages(1).Controls![HireDate].Visible = False
        Me!TabCtl0.Pages(1).Controls![ReportsTo].Visible = False
     End If
   End Sub


STATUS

This behavior is by design.
