    Get previous and next sibling from same type

    Hi,

    I am trying to implement "Next" and "Previous" buttons in a blog article page. For doing so I simply need to get the next/previous siblings of the current page (from the same type).

    Couldn't find a proper answer for this issue.

    Cheers

    Can't believe I missed it.

    CurrentPage.Next()
CurrentPage.Previous()

    But how can I check their type & visibility?

    Hi Eli,

    Mu much better to use these lines:

    var prev = Umbraco.AssignedContentItem.Previous();
var next = Umbraco.AssignedContentItem.Next();

    How to check visibility and document type alias:

    var isVisible = prev.IsVisible();
var documentTypeAlias = prev.DocumentTypeAlias;

    Thanks,

    Alex

    Thanks Alex, but I want to retrieve the next sibling that is visible from the same type, and not just get the next/previous one and check if they are visible and their type. Is there an short query for that or should I iterate over all of my siblings until I get one that fits me?

    Cheers

    Hi Eli,

    Try using:-

    Getting The Current Page Via The Database To get the content via the database, so you can write to it as well, you need to use a different API, like so:

    var currentPageId = UmbracoContext.Current.PageId;
    IContent content = ApplicationContext.Current.Services.ContentService.GetById(currentPageId);

    Hi Bharti

    Never user "ContentService" for displaying content.

    "ContentService" is for making changes in the database. It's a heavy method, on the pages user IPublishedContent always!

    Have a look at "Common Pitfalls & Anti-Patterns" and never do it like that:

    Thanks,

    Alex

    Hi All,

    Here is what I have done. Seems to do the trick.

    Obvs switch out my CaseStudyDetailsPage for IPublishedContent or whatever page type you are using.

    IEnumerable

    CaseStudyDetailsPage nextPage = null;
CaseStudyDetailsPage previousPage = null;

if(siblingCaseStudyPages != null && siblingCaseStudyPages.Count() >= 2)
{
    previousPage = siblingCaseStudyPages.LastOrDefault(x => x.SortOrder < caseStudyDetailsPage.SortOrder);
    nextPage = siblingCaseStudyPages.FirstOrDefault(x => x.SortOrder > caseStudyDetailsPage.SortOrder);
}
