Hello everyone,

I have just started using Umbraco after a very long time, and I would appreciate if someone could me help with nuPickers.

I have implemented nuPickers.XmlPrefetchListPicker in a DocumentType named "Article". When the content-editor creates an article under one of the categories, the nuPicker allows them to select other associated categories (folder) for the article too.

Eg: When an article is created under the Sports Category, he/she would be listed with all other categories in the nuPicker such as "News", "Current Affairs", "Technology" etc. So if the content-editor wishes to display this article in "Current-Affairs", they could select the same from the nuPicker.

How do I query all the documents with datatype article and the nupicker has a value ="Technology" selected.

Here is my code :

var content2 = help.TypedContent(1048)
            .Children
            .Where(c => c.DocumentTypeAlias == "article")

            .Select(obj => new Article()
            {
                CategoryName = obj.Name,
                CategoryId = obj.Id,
                Description = obj.GetPropertyValue<string>("description")
            });

I appreciate if someone could help me with the second where clause
