Need to Pull Data from Multiple PageLists

Vote:
 

Currently, we have a section of our site that is structured as follows:

Archives (PageList)

2013(PageList)

News Story (News Article)

News Story (News Article)

2012 (PageList)

News Story (News Article)

 

The issue is I need to pull the news stories despite the year and display them on our home page. When I set "Archives" as the data source, it only pulls "2013" and "2012". Is there a way to skip over the secondary PageLists so I can display the news stories.

I've tried to filter using the following:

private void HomeNewsPageList_Filter(object sender, FilterEventArgs e)
        {
            var pages = e.Pages;
            for (int i = pages.Count - 1; i > -1; i--)
            {
                if (pages[i].PageName as string == PageBase.Translate("/news/archivesheading") || pages[i].PageTypeName as string != "News Article" || pages[i].PageName.Length == 4)
                {
                    pages.RemoveAt(i);
                }
            }
        }

 

This seems to be a start in the right direction to exclude the secondary PageList, but I cannot display the respective children. Any suggestions?

 

Thanks in advance!

You coud try to set the DataSource on your list in pageload instead of directly in the control. You need to fetch descendants, not only children.

This should work:

protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);

List<PageReference> pageRefs = DataFactory.Instance.GetDescendents(LinkToArchivePage);

PageDataCollection filteredCollection = new PageDataCollection();

foreach (PageReference pageReference in pageRefs)
{
PageData page = DataFactory.Instance.GetPage(pageReference);
if (page.PageTypeName == "News Article")
filteredCollection.Add(page);

}

yourPageList.DataSource = filteredCollection;

}

I didn't see this sooner. Thank you for the prompt reply. I'm now subscribed to email notifications on this thread so I won't miss anything again. The code builds, but now I realize I haven't handled filtering the results by the currently selected language. Any thoughts? After researching, it seems maybe I should have gone down the "FindPagesWithCriteria" approach, but I'm wondering if there's a way to modify what you've provided without having to start over. I tried the code below and it almost works, but now is pulling in the page lists as well (2013,2012 from the first post) well.

Thanks!

    


protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (!IsPostBack) { this.LanguageString = (System.Globalization.CultureInfo.CurrentCulture).ToString(); HomePageNewsList.PageLinkProperty = PageLinkProperty; if (MaxCountProperty != null && CurrentPage[MaxCountProperty] != null) { HomePageNewsList.MaxCount = (int)CurrentPage[MaxCountProperty]; } // Hide the whole control if the list is empty //this.Visible = HomePageNewsList.DataCount > 0; PageReference NewsPullPage = CurrentPage.Property["MainListRoot"].Value as PageReference; IList<PageReference> pageRefs = DataFactory.Instance.GetDescendents(NewsPullPage); PageDataCollection filteredCollection = new PageDataCollection(); foreach (PageReference pageReference in pageRefs) { PageData page = DataFactory.Instance.GetPage(pageReference); if (page.PageTypeName == "News Article" && page.LanguageBranch == LanguageString && page.PageName.Length != 4) filteredCollection.Add(page); } HomePageNewsList.DataSource = filteredCollection; HomePageNewsList.DataBind(); } }

I think it is this line that make the 2012, 2013 pages appear in your list:

HomePageNewsList.PageLinkProperty = PageLinkProperty;

You kind of set the datasource twice I think. I do not think it is possible for the 2012 and 2013 pages to be added with the filter (the if-sentence) in place.

 

Try to remove the codeline mentioned and I think it should work.
