In PropertyGrid\XTPPropertyGridInplaceEdit.cpp change line 222 to

    CWnd* pParent = GetAncestor(GA_ROOT);

    and line 233 to

    CWnd* pWndNext = pParent->GetNextDlgTabItem(m_pGrid, (GetKeyState(VK_SHIFT) < 0));

Add the following function to PropertyGrid\XTPPropertyGridView.cpp

void CXTPPropertyGridView::_ForwardFocus()
{
    CWnd* pRoot = GetAncestor(GA_ROOT);
    CWnd* pWndNext = pRoot->GetNextDlgTabItem(m_pGrid, (GetKeyState(VK_SHIFT) < 0) );
    if (pWndNext != NULL)
    {
        pWndNext->SetFocus();
    }
}

Add the folloing lines to CXTPPropertyGridView::OnKeyDown

    if (nChar == VK_TAB && (!pItem || pItem->IsCategory()) )
    {
        _ForwardFocus();
    }

How can I make the control forward the tab key to the dialog? I want to move the focus to the next control, when the tab key is pressed.

Thanks, Italo
