Easier way to display page .HasValue

Umbraco Cloud

Umbraco 8
Is there any easier way to do this, can someone point me in the right direction.

I have a number of case histories items that have a value (eg "Car Park") via a drop down menu "Catagory". I display all the items on a page (Case Histories) but also have a page for each item (ie Car Park) and wish to display just the items that relate to that page.

I can do this by creating a document type for each page ie "Case History Car Park" and adding the razor.
```
    var casesort = Model.Content.Site().FirstChild("caseHistoryPage").Children()
                    .Where(x => x.HasValue("Catagory") && x.GetPropertyValue<string>("Catagory").Equals("Car Park"));
```
Is there a way that I can use the Document type "Case history" for all pages or do I have to create a Document type for each (Car Park, Maintenance, Painting etc)

First of all Model.Content has been changed to "just" Model in v8

I don't think I understand your question right, but would't you just want to add the "Car park" as a value from the page you are on?

something like:
```
var casesort = Model.Site().FirstChild("caseHistoryPage").Children()
                .Where(x => x.HasValue("Catagory") && x.GetPropertyValue<string>("Catagory").Equals(Model.Catagory));
```

Thanks Soren. Let me try an explain further.

I have a number of case histories

When the client adds a new case history they have a drop down menu to choose the catagory of the Case history.

All the Case histories are displayed on the Case History page but I also wish to display just the case histories that relate to the page under services. ie the page /Services/Car Park Upgrades to display the items that just have the catagory "Car Park". The page /Services/Painting to display the items that just have the catagory "painting".

Does that help?

Again, you just needs use a property from the page you are on, to filter the list of related page, like in the code i posted
