How to implement jumping to a label when I click on hyperlink (like in HTML)?

I imagine using Tag attribute to search through page but maybe there is en easier way to do it?
Any command to position on destination element (I want it to be visible at the beginning of the screen)?
Page have <ScrollViewer> of course.

Hi,

Here some code to try

void CMarkupPadView::OnHyperlinkClick(CXTPMarkupObject* pSender, CXTPMarkupRoutedEventArgs* pArgs)
{
if (pSender->IsKindOf(MARKUP_TYPE(CXTPMarkupHyperlink)))
{
CXTPMarkupScrollViewer* pView = MARKUP_DYNAMICCAST(CXTPMarkupScrollViewer, m_pUIElement->FindName(L"scroll"));
CXTPMarkupUIElement* pText = MARKUP_DYNAMICCAST(CXTPMarkupUIElement, m_pUIElement->FindName(L"New"));

  if (pView && pText)
  {
   CRect rc = pText->GetMarkupContext()->GetClientBoundingRect(pView);
   CRect rc1 = pText->GetMarkupContext()->GetClientBoundingRect(pText);

pView->SetScrollPos(SB_VERT, rc1.top - rc.top);
}

pArgs->SetHandled();
}
}

and in markup add names "scroll" for ScrollView :

<ScrollViewer x:Name="scroll" ...

Finding element and setting scroll position works well, but GetClientBoundingRect is private :(

I know my element is visual and scroll start from the beginning of the page so I did like this:

if (pView && pText){
   CXTPMarkupVisual* pVisual = (CXTPMarkupVisual*)pText;
   CRect rc = pVisual->GetBoundRect();
   while (pVisual != 0)
   {
      rc.OffsetRect(pVisual->GetVisualOffset());
    pVisual = pVisual->GetVisualParent();
   }
   pView->SetScrollPos(SB_VERT, rc.top);
}

When I look inside this metod it's not easy to understand it without any help. Hope you'll add Markups classes to Help soon.
