i have created on ribbon control with 4 tabs each holding one tabpage and all are inside one tabpagecollection .
Now when i click on File (New)tab i want to generate a new tab containing a tabpage dynamically and to be shown at the end (after 4th tab)

Is it possible to generate and a new tab dynamically by clicking on existing tab .

What i have done is
CExtRibbonNodeTabPage * pRibbonNodeTabPage =new CExtRibbonNodeTabPage( 0L, m_pRibbonNode, _T("Test") );
pRibbonNodeTabPageCollection1->InsertNode( NULL,pRibbonNodeTabPage);

where pRibbonNodeTabPageCollection1 already contains 4 tabs and it present in my ribbonnode m_pRibbonNode.
m_pRibbonNode->InsertNode( NULL, pRibbonNodeTabPageCollection1 );

But still i could not see the newly added tab "Test" in my ribboncontrol.

What changs should i make on suggest a method to do such thing if possible

Thanks in advance.

Step 1: Add the following virtual method to the ribbon bar class to fix a small bug in it. This is required for updating the dynamic content correctly:

virtual void _RemoveAllButtonsImpl();
void CExtRibbonPage::_RemoveAllButtonsImpl()
    m_pQACEB = NULL;
Step 2: The following code should be invoked to remove the content of the ribbon:
INT nSel = 0; // needs to restore selected tab
    if( m_pRibbonNode != NULL )
        // remember selection index
        nSel = m_wndRibbonBar.Ribbon_GetTabPageRootNode()->PageSelectionGet();
        // delete content
        m_wndRibbonBar.SetButtons( NULL );
        delete m_pRibbonNode;
        m_pRibbonNode = NULL;
Step 3: Create the new content in the same way as it is done in the CMainFrame::_InitRibbonBar() method in the RibbonBar sample. Use the nSel value when calling the pRibbonNodeTabPageCollection->PageSelectionSet() code when initializing the ribbon’s content.

Step 4: Make the changes visible on the screen.

m_wndRibbonBar.SetButtons( NULL ); this statement gives call to _RemoveAllButtonsImpl() and removes everything created before.
Is there a way out that i could add any a new tab without removing previous content and just "append" the newly created tab at any position in between it.

You don’t need to remove all the content. Just use methods of the CExtCustomizeCmdTreeNode class and then just invoke the CExtRibbonBar::SetButtons() method to refresh the ribbon bar’s content.
