How to display a property in all the existing language versions on the same page?

Hello, I'm trying to display the following link to a pdf in all language versions on the same page. This pdf property is unique per language. Also available in: English Français Español I can't seem to be able to extract the correct value in the French or the Spanish. I keep getting the English one instead. I'm not sure what is wrong in the code below. Any help would be greatly appreciated.


        public string GetPDFLink()
        {
            //private PageData langPage; This is declared elsewhere.

            LanguageBranch lb = LanguageBranch.Load(DocumentPage.LanguageBranch);
            string _getPDFLink = "";

            if (lb.Name == "Default")
            {
                _getPDFLink = (string)DocumentPage["varFilePath"];
            }
            else if (lb.Name == "FR")
            {
                EPiServer.Core.LanguageSelector selectorFR = new EPiServer.Core.LanguageSelector("FR");
                langPage = EPiServer.Global.EPDataFactory.GetPage(DocumentPage.PageLink, selectorFR);
                _getPDFLink = (string)langPage["varFilePath"]; // This should be the value from the French version of the page
            }
            else if (lb.Name == "ES")
            {
                EPiServer.Core.LanguageSelector selectorES = new EPiServer.Core.LanguageSelector("ES");
                langPage = EPiServer.Global.EPDataFactory.GetPage(DocumentPage.PageLink, selectorES);
                _getPDFLink = (string)langPage["varFilePath"]; // This should be the value from the Spanish version of the page
            }

            return _getPDFLink;
        }

If the link to the pdf is stored in a property (varFilePath) you should use the DataFactory.GetLanguageBranches method instead of the LanguageBranch class to get the available language versions. Here is some code to get you on the track:


// Only brain compiled - put it into PageLoad
PageDataCollection langVersions = Global.EPDataFactory.GetLanguageBranches(CurrentPage.PageLink);
PageDataCollection pagesWithPdfLinks = new PageDataCollection();
foreach (PageData page in langVersions)
{
  // Check that it is not the same lang as the currently loaded one
  // Also check that the page has a value for the pdf link
  if (CurrentPage.LanguageBranch != page.LanguageBranch &&
      page["varFilePath"] != null)
  {
    // We have a language version of the page
    pagesWithPdfLinks.Add(page);
  }
}
lstPdfLinks.DataSource = pagesWithPdfLinks;
lstPdfLinks.DataBind();

Now you have a collection of page language versions that have a value for the pdf link. It does not contain the currently showing language version. It has been bound to a PageList control, which could look like this:



  
    Also available in: 
  
  
   ]]>

and you need the GetLanguageDisplayName method in your code behind file:


protected string GetLanguageDisplayName(string languageBranch)
{
  return LanguageBranch.Load(languageBranch).Name;
}

I think this should do the trick, at least it should give you some pointers on how to solve it. /Steve

Thank you Steve. This worked great. Now, I will use this same function for a NewsList control where each of the Items iterated will display this same function. It will look something like this. ---------------------------------------------- PageName Also available in: English French Spanish ---------------------------------------------- PageName Also available in: English French Spanish ---------------------------------------------- PageName Also available in: English French Spanish ---------------------------------------------- How would you apply the function you indicated? I tried the following in the ascx:


]]>" runat="server">
            
                <%#ContainerPage(Container.CurrentPage)%>
                <%----%>
                <%# GetLanguageDisplayName(Container.CurrentPage.LanguageBranch) %>
                <%----%>

And the following in the cs:


        public PageDataCollection pagesWithPdfLinks = new PageDataCollection();
        public PageDataCollection langVersions;
        protected EPiServer.WebControls.PageList lstPdfLinks;

        public void ContainerPage(PageData pr)
        {
            langVersions = Global.EPDataFactory.GetLanguageBranches(pr.PageLink);
            
            foreach (PageData page in langVersions)
            {

                // We have a language version of the page
                pagesWithPdfLinks.Add(page);

            }

            lstPdfLinks.DataSource = pagesWithPdfLinks;
            lstPdfLinks.DataBind();

        }

        protected static string GetLanguageDisplayName(string languageBranch)
        {
            if (LanguageBranch.Load(languageBranch).Name == "Default")
                return "English";
            else
                return LanguageBranch.Load(languageBranch).Name;
        }

Needless to say, it doesn't work as smoothly as the one you suggested. Any advice?
