Hi Dave,

Can you rewrite this line:

var entries = blogArchive.Children.Where(x => x.Properties.Where(a=>a.PropertyTypeAlias=="categories" && a.HasValue=="Test"));

Maybe like that :

var entries = blogArchive.Children.Where(x => x.GetPropertyValue<string>("categories") == "Test"));

Thanks, Alex

I tried but no blog entries returned. No exception which is good but not the solution. categories is a property inside a collection of each entry which i feel is the big clue.

Hi Dave, 

If I understand your questions correct you have a home page node, in your Umbraco installation, and at the same level you have the Articulate blog node. And then you want to display blogposts from a category on your home page. See the image below.

With this code you should get blogpost where the category is Test.

@{
    var blogRoot = Umbraco.ContentAtRoot().DescendantsOrSelf("Articulate").FirstOrDefault();
    var blogArchive = blogRoot.Children.First();

    foreach(var blogposts in blogArchive.Children.Where("Visible").Where("categories == @0","TestCategory")){ 
        <p>@blogposts.Name</p>
    }

    
}

The first thing I do is go the root of the Umbraco tree, and from there you need to find the blog node, and then we find the first children in our case it´st he blog archive. Then I am looping though each blogpost where the category is set to Test.

You can use to make a partial view or a partial view macro file, the code you should use is the same.

For the documentation about the .ContentAtRoot take a look here: https://our.umbraco.org/documentation/Reference/Querying/UmbracoHelper/#ContentAtRoot%28%29

And here is also a strongly typed vesion available: https://our.umbraco.org/documentation/Reference/Querying/UmbracoHelper/#TypedContentAtRoot%28%29

Hope this helps and don't hesitate to ask again,

Something like this?

var root = Model.RootBlogNode;
//first child of type ArticulateArchive
var blogArchive = root.Children.OfTypes("ArticulateArchive").First();
//To lookup the 'last' item (assuming you mean 'latest' item)
var entries = blogArchive.Children
    .OrderByDescending(x => x.UpdateDate)
    //Get the latest item that has been tagged with a category of "Test" (case insensitive)
    // categories are stored as CSV so we split
    .First(x => x.GetPropertyValue<string>("categories").Split(',').InvariantContains("Test"));

I appreciate the help.

Dennis (you can see below the exception/error) using blogArchive.Children.Where("Visible").Where("categories == @0","TestCategory")) You can see a few other variations that i tried without success

Shannon I did get some success with (shown here) which is good. How would I get all blog entries that have a category of Test (or .net features). I noticed the First in the syntax but wasn't sure how i could change out to get all of the blog entries.

var entries = blogArchive.Children.First(x=>x.GetPropertyValue<string>("categories").Split(',').InvariantContains(".NET Features")); //works

thanks for the support.

I got object reference not set to an instance of an object on the .Where line

However I was able to modify the where clause slighted so that I avoid those posts that have null value via the following which seemed to work

.Where(x => x.GetPropertyValue<string>("categories") !=null && x.GetPropertyValue<string>("categories").Split(',').InvariantContains("Test"))

The ToArray was a missing piece. Thanks again!

Yes, it's because you need a null check there, if the property is empty, it will be null

is working on a reply...
