Is it possible to filter news topics in Alloy site with month and year?

Hi,

I am using CMS 11 with .NET Framework 4.6 and I am trying to implement a filter for news articles for news and events list to filter them based on the month or year of publish.

Has anyone attempted it or does anyone has any reference to how it can be done? Please let me know,

I am also trying to add pagination to the list. If anyone has any references, please let me know.

With risk of sounding like we're on Stackoverflow: what have you tried so far? :)

I have tried JavaScript to implement pagination on the NewsPage list.
I couldn't find any option within EPIServer as all the current documentation refers to CMS 12 not 11.

Are you in the DXP? If so this should all be done using Search & Navigation https://world.optimizely.com/documentation/developer-guides/search-navigation/NET-Client-API/

If not you should use a different search system such as direct Elastic, Lucene or some sort for these types of filters.

Or if it's only about filtering by month/year: automatically group the article pages under container pages, so that you can filter by invoking GetChildren() on a single container. There are many roads to Rome... :)

I would never do it like that for any production site. Even with the in memory cache any filtering and logic can become very expensive if the number of pages is remotely large and you'd have to do a lot of caching

Not on DXP but I'll check the article.

@Ted The articles are under the container page. Any reference you can direct me to use the GetChildren() option?

If the only requirement is to filter by year or month - i.e. list -all- pages within that year or month - I think it would be difficult to get better performance than a single GetChildren() call. I use it quite often, and I would challenge anyone to optimize it further (for the use cases I'm using it for) at a cost acceptable to the client. :)

@Anant: GetChildren() is part of IContentLoader. You pass it a ContentReference and it returns content directly underneath it (it's not recursive). It is cached. You need to use FilterForVisitor on the child content to ensure you only return content the current user has permissions for.

Well, I second using Search & Navigation (if it's available) although there are many, many ways to achieve this.

You can easily use sorting (https://world.optimizely.com/documentation/developer-guides/search-navigation/NET-Client-API/searching/Sorting/) with skip & take (https://world.optimizely.com/documentation/developer-guides/search-navigation/NET-Client-API/searching/Pagination-Skip-and-Take/) to achieve pagination.

I'm sure this functionality has been built a lot of times, but how you design and build it would be based on your specific requirements and stack.

Search & Navigation is one of the best option to achieve that.

Here are the implementations to get inspired:
