Traversing - get next node

Using Umbraco And Getting Started

Umbraco 7
Dear Umbraco Team

I have a node with a few child nodes. i would like to render content from a node between the first and last node. i am able to get content from both first and last child nodes using the following code
```
 @{ var firstChild = @Model.Content.Children.First();}
 @{ var lastChild = @Model.Content.Children.Last();}
```
But when i try the following code i get YSOD
```
 @{ var nthChild = @Model.Content.Children.Next(1);}
```
Am i missing some thing ? Any assistance would be great

Thanks Dibs

You can use the Siblings() extension.

Or you could use FollowingSibling which has a few overloads.

@Model.Content.FollowingSibling("textPage",true)

The gets the next sibling, and if you're on the last one, it'll wrap round to the first.

Or something like this...
```
@{
var nodes = Model.Content.Siblings().OrderBy( x => x.SortOrder);
}

@foreach (var n in nodes)
    {
<p> n.Name</p>

 }
```

Hi Dibs.

So the Next() method is an extension method for a singe IPublishedContent model, and it returns the node next to the current model in the tree.

Your are trying to use it on a List of IPublishedContent, and that does not work.

Instead if you browse a child node and have this in your view: @Model.Content.Next(), that would return the next child after your current browsing child.

Make sure however to null check, because I think the .Next() method throws a null reference exception if the child your browsing does not have a next child or is the only child for instance.

Hopefully this makes sense.

Also have a look at the Querying/Traversing documentation, that might help you: https://our.umbraco.org/documentation/reference/templating/mvc/querying

Best of luck!

Cheers Paul & Dennis

While you were giving me feedback, I got the following to work.

@{ var child = @Model.Content.Children.First();}

@child.Next(nth).GetPropertyValue("property")

Thanks Dibs
