[SOLVED] Need to display first n items from each category in Razor using Umbraco

Need to display first n items from each category in Razor using Umbraco

I am new to Umbraco. I have a list of items in a content named Videos. Each item have a specific category. I need to retrieve 'n' number of items from each category. Some one please help. Also am using MixItUp jquery plugin to display the items.

// this will bring up all items from the list
    var items = Umbraco.TypedContent(Model.Content.Id).Children.Where(x => x.DocumentTypeAlias == "videoItem" && x.IsVisible());

// Here am trying to bring 5 items under category "Testimonial"

    var allItems = items.Where(x => x.GetPropertyValue("category") == "Testimonial").Take(5);

But I didn't found any output. Please help.

Solution

Your second line of code should read:

var allItems = items
    .Where(x => x.GetPropertyValue<string>("category") == "Testimonial")
    .Take(5);

Rather than simply cast the result to string, this will try and convert the object to the desired type if it isn't already - see here.

If you're using the new ModelsBuilder (which is awesome) you also have the option of strongly typing the whole process.

var items = Model.Content.Children<VideoItem>().Where(x => x.IsVisible());

var allItems = items.Where(x => x.Category == "Testimonial").Take(5);
