Get subchild of multiple node using single query

Features

Umbraco 7
Hello,

I Want to display product category and its product. I have displayed it.

My node structure is like :
```
Home
    Product Category-1
        Product Category List-1.1
            Product-1.1.1
            Product-1.1.2
        Product Category List-1.2
            Product-1.2.1
            Product-1.2.2
    Product Category-2
        Product Category List-2.1
            Product-2.1.1
            Product-2.1.2
        Product Category List-2.2
            Product-2.2.1
            Product-2.2.2
```
Now, I want to get
Product-1.1.1, Product-1.1.2, Product-1.2.1, Product-1.2.2, Product-2.1.1, Product-2.1.2, Product-2.2.1, Product-2.2.2 in single query. How can I get that?

Thank You.

Hi Dipa,

You can do something like this :

@using Umbraco.Core.Models
@using Umbraco.Web
@using Umbraco.Web.Mvc
@inherits UmbracoViewPage
@{
    var homeNode = Model.AncestorOrSelf("DocTypeAliasOfHomeNode");

    List<IPublishedContent> categories = new List<IPublishedContent>();

    if(homeNode != null)
    {
        categories = homeNode.Descendants("DocTypeOfCategory").ToList();
    }
}

@if(categories.Any())
{
    <ul>
        @foreach(var category in categories)    
        {
            <li><a href="@category.Url">@category.Name</a></li>    
        }
    </ul>
}

Of course you need to replace the doctype aliases with the correct ones. Also when having a lot of categories the .Descendants call can be a performance hit. So make sure that you cache this information.

Hi Dave,

Your help is really helpful to me. But now, in project, node structure get changed. Now it is like below :

Home
        Page-1
        Page-2
Product Category-1 
        Product Category List-1.1
            Product-1.1.1
            Product-1.1.2
        Product Category List-1.2
            Product-1.2.1
            Product-1.2.2 
Product Category-2
        Product Category List-2.1
            Product-2.1.1
            Product-2.1.2
        Product Category List-2.2
            Product-2.2.1
            Product-2.2.2

Now how can I get only products?

Thanks,

Dipa

Thanks Dave for replying soon.

But my doubt is :

Document Type of Home node and Product category node is different. Then which document type I have to define as DocTypeAliasOfHomeNode ? Of home node or Product Category node ?

Thanks,

Dipa

Hi Dipa,

Maybe i should explain the code a bit.
```
 var homeNode = Model.AncestorOrSelf("DocTypeAliasOfHomeNode");
```
This code will traverse up the tree from your current page and will find the ancestor of the type homepage. If it is executed on the homepage it will return the homepage as well. You should replace "DocTypeAliasOfHomeNode" with the actual doctype alias of your home node.

Then this piece of code will get all your pages under the "Home" node of the specified document type, no matter on what level they are in the tree.
```
List<IPublishedContent> categories = new List<IPublishedContent>();

    if(homeNode != null)
    {
        categories = homeNode.Descendants("DocTypeOfCategory").ToList();
    }
```
You should replace "DocTypeOfCategory" to the actual doctype of your product.

Did you replace "DocTypeAliasOfHomeNode" with the doctype alias of your home documenttype ?

Or maybe you can try this instead :
```
var homeNode = Model.AncestorOrSelf("DocTypeAliasOfHomeNode");
```

So your product categories are on the same level as the homepage ?

You can probably change your code to this :
```
var homeNode = Umbraco.TypedContentAtRoot().First();
```
