Ok it works now :-)

Changed the code in on ToolHitTest

...
 HTREEITEM hTreeItem = HitTest(point, &nFlags);  // GetItemFromPoint(point);
 if(pTI && hTreeItem)
 {
       nHit = reinterpret_cast<INT_PTR>(hTreeItem);

...

Once again - thank you for your help!

Thank you for your help but it doesn't work -> any idea?
I use toolkit version 13.4. My class is derived form CUIXTreeCtrl which is based on CXTTreeCtrl.

here is my code:

//-----------------------------------------------------------------------------
int CUIActiveUsersTreeCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
//-----------------------------------------------------------------------------
{
    if (CUIXTreeCtrl::OnCreate(lpCreateStruct) == -1)
        return -1;

    // Create the image list used by the tree control.
    if ( !m_imageList.Create( 16, 16, ILC_COLOR24 | ILC_MASK, 1, 1 ) )
    {
        TRACE0("Failed to create image list.\n");
        return -1;
    }

    // load the tree images bitmap and add it to the image list.
    m_bitmap.LoadBitmap( IDB_IMGLIST_VIEW );
    m_imageList.Add(&m_bitmap, RGB(255,0,255));  

    // Set the image list for the tree control.
    SetImageList( &m_imageList, TVSIL_NORMAL );

    m_TTContext.SetStyle(xtpToolTipMarkup);
    m_TTContext.ShowTitleAndDescription(TRUE);
    SetToolTips(NULL);
       
    return 0;
}

BOOL CUIActiveUsersTreeCtrl::PreCreateWindow(CREATESTRUCT& cs)
{
    if ( !CUIXTreeCtrl::PreCreateWindow( cs ) )
        return FALSE;

    // Set the style for the tree control.   
    cs.style |= TVS_DISABLEDRAGDROP;   
    cs.style &= ~TVS_HASLINES;
    cs.style &= ~TVS_LINESATROOT;
    cs.style &= ~TVS_HASBUTTONS;

    // If non-xp mode, add a client edge border to the tree.
    if (!xtAfxData.bXPMode)
    {
        cs.dwExStyle |= WS_EX_CLIENTEDGE;
    }

    cs.style |= TVS_NOTOOLTIPS;

       return TRUE;
}

CString CreateMarkupTool(LPCTSTR strCaption, LPCTSTR strDesc)
{
     
    CString strHTML;
    strHTML.Format(
            _T("<StackPanel Margin='1' MaxWidth='200'>")

            _T("</StackPanel>"),
        strCaption, strDesc);
   
    return strHTML;
}

INT_PTR CUIActiveUsersTreeCtrl::OnToolHitTest(CPoint point, TOOLINFO* pTI) const
{
    // check child windows first by calling CControlBar
    INT_PTR nHit = CWnd::OnToolHitTest(point, pTI);
    if (nHit != -1)
        return nHit;

    HTREEITEM hTreeItem = GetItemFromPoint(point); // this is yust a helper to get item under cursor
    if(hTreeItem)
    {
        nHit = (INT_PTR) hTreeItem;
        m_TTContext.FillInToolInfo(pTI, GetSafeHwnd(), CRect(point, CSize(100, 100) ), nHit, CreateMarkupTool(_T("XXX Test"), _T("YYY TEST2")));

    }

How can i add an individual tooltip to each tree control?
It would be nice if this tooltip could be of type xtpToolTipMarkup!

Please help!
