Question to CodeJock Techs

what i Call Dynamic is a way to create a template example
<Page xmlns=...
<Grid...
         <StackPanel ....
              <Dynamic.1></Dynamic.1>
         </StackPanel

from the CXTPMarkupBuilder::Parse
{
           switch(t)...
             case CXTPMarkupParser::tokenTagEnd:
                       ...
                       if(wcsncmp(lpszTagName), L"Dynamic ",7) == 0)
                          Call Owner via a SendMessage with StackPanel             object as WPARAM and Builder as LPARAM
                   ...
}

Owner::OnDynamicAdd(WPARAM wParam, LPARAM lParam)
{
           CXTPMarkupStackPanel* pObject = (CXTPMarkupStackPanel*)wParam;
    CXTPMarkupBuilder * Builder = (CXTPMarkupBuilder *)lParam;

    CXTPMarkupTextBlock* pTextBlock1 = MARKUP_CREATE(CXTPMarkupTextBlock,this);
    pTextBlock1->SetTextWrapping(1);
    pTextBlock1->SetText(L"You can increment or decrement the value of this"
                        L"textbox by simply clicking the mouse, hold and drag"
                        L"up or down, right or left. Release when happy,with the value.");
    pTextBlock1->SetMargin(5, 0, 5, 0);
    pTextBlock1->SetBackground(new CXTPMarkupSolidColorBrush(RGB(0xFF, 0, 0)));
    pTextBlock1->SetForeground(new CXTPMarkupSolidColorBrush(RGB(0xFF, 0xFF, 0xFF)));

    pObject->GetChildren()->Add(pTextBlock1);

}
hope is not to confusing just a better wat to fill in the markup dynamically
thanks guys

Hi,

You almost find solution :)

Here how it should work.

1. We add new class and register its Tag:

class CMyDynamicMarkup : public CXTPMarkupGrid
{
DECLARE_MARKUPCLASS(CMyDynamicMarkup)

void SetContentObject(CXTPMarkupBuilder* pBuilder, CXTPMarkupObject* pContent);
};

IMPLEMENT_MARKUPCLASS(L"Dynamic", CMyDynamicMarkup, CXTPMarkupGrid);

void CMyDynamicMarkup::RegisterMarkupClass()
{
}

2 Add your dynamic code in SetContentObject

void CMyDynamicMarkup::SetContentObject(CXTPMarkupBuilder* pBuilder, CXTPMarkupObject* pContent)
{
if (IsStringObject(pContent))
{
// Here we can use content as parameter;

  CXTPMarkupTextBlock* pTextBlock1 = MARKUP_CREATE(CXTPMarkupTextBlock,pBuilder->GetMarkupContext());
  pTextBlock1->SetTextWrapping(1);
  pTextBlock1->SetText(L"You can increment or decrement the value of this"
   L"textbox by simply clicking the mouse, hold and drag"
   L"up or down, right or left. Release when happy,with the value.");
  pTextBlock1->SetMargin(5, 0, 5, 0);
  pTextBlock1->SetBackground(new CXTPMarkupSolidColorBrush(RGB(0xFF, 0, 0)));
  pTextBlock1->SetForeground(new CXTPMarkupSolidColorBrush(RGB(0xFF, 0xFF, 0xFF)));

  GetChildren()->Add(pTextBlock1);

}
}

3. And Markup is

<Page>
<Dynamic>parameter</Dynamic>
</Page>

what if you want to replace with a row of may be elements
like so
void CMyDynamicMarkup::SetContentObject(CXTPMarkupBuilder* pBuilder, CXTPMarkupObject* pContent)
{
    if (IsStringObject(pContent))
    {
        // Here we can use content as parameter;
        for(int x=0;x<10;x++)
        {
                CXTPMarkupTextBlock* pTextBlock1 = MARKUP_CREATE(CXTPMarkupTextBlock,pBuilder->GetMarkupContext());
                pTextBlock1->SetTextWrapping(1);
                pTextBlock1->SetText(L"1You can increment or decrement the value of this"
                    L"textbox by simply clicking the mouse, hold and drag"
                    L"up or down, right or left. Release when happy,with the value.");
                pTextBlock1->SetMargin(5, 0, 5, 0);
                pTextBlock1->SetBackground(new CXTPMarkupSolidColorBrush(RGB(0xFF, 0, 0)));
                pTextBlock1->SetForeground(new CXTPMarkupSolidColorBrush(RGB(0xFF, 0xFF, 0xFF)));

            if(pTextBlock1)
                GetChildren()->Add(pTextBlock1);
        }

    }
}
