Bump... Can CJ confirm if this is a bug or not.

What's the purpose of a Workspace_SelectedChanged event if it does not fire when a different tab is selected ?

(current version still has this "behaviour")

BTW, the proposed workaround only works when the user actually "clicks" on the tab. For all other methods of selecting a different tab, this does not work (e.g. click on the contained form, keyboard, etc)

[edit] For those interested, until this is fixed, the way to go is using a timer and checking the Selected property. It changes as expected:

Private Sub FastTimer_Timer()
Dim TabID As Long, GroupID As Long
Static OldWorkspaceTabID As Long, OldWorkspaceGroupID As Long   '2009-12: selectionchanged does not work between groups in 13.2

TabID = Me.CB.TabWorkspace.Selected.Index
GroupID = Me.CB.TabWorkspace.FindGroup(Me.CB.TabWorkspace.Selected)
If TabID <> OldWorkspaceTabID Or GroupID <> OldWorkspaceGroupID Then
   Me.WorkspaceSelectionChanged
     OldWorkspaceTabID = TabID
     OldWorkspaceGroupID = GroupID
end if
end sub

Public Sub WorkspaceSelectionChanged()

Set FocusForm = Me.ActiveForm
' use this FocusForm to reference the active tab
End Sub

Using MDI Tabs the Workspace event _SelectedChanged is fired each time a different Tab is clicked by user. That is good.

But when I have several Groups of Tabs, the _SelectedChanged event does NOT always fire when user clicks different Tab if the Tab is in a different Group. It only behaves correctly if we stay in the same Group.

To explain better: It seems each Group retains its own "Current Tab". When user clicks on any "current Tab" the Changed event does not fire -- even if Tab is in a different Group.

I expect this is Working As Designed (ie. not a bug). But how can I detect when user clicks in a different Group ?? eg. is there a Group_Changed event?

WORKAROUND -- the Workspace_BeforeItemClick event is correctly fired for ALL times when user clicks on a Tab. Even if it is current Tab or in a different Group. So with a bit of logic I can use this event to get around the problem with _SelectedChanged event.

But please still comment if I have missed something or there is a better way.
