So... how would I use this IN a custom grid docType

Nested Content Feedback
So, using both your AWESOME new packages together... how would i get at the properties of a nested content item in a grid docType? I can get the name like this... but how do i list the custom properties?
```
@inherits Umbraco.Web.Mvc.UmbracoViewPage

    @{ 
        var items = Model.GetPropertyValue>("CarouselItems");

        foreach(var item in items) { 
            // Do your thang...
        @item.Name
        } 
    }
```

Hi Bob,

Thanks for the praise! :-)

With accessing the Nested Content values, you can use the IEnumerable<IPublishedContent> type.
```
var items = Model.GetPropertyValue<IEnumerable<IPublishedContent>>("CarouselItems");
```
Then inside the loop, you can access the item's inner properties using GetPropertyValue<T>:
```
foreach(var item in items)
{
    // Do your thang...
    @item.Name

    @item.GetPropertyValue("propertyAlias")
    // ... or ...
    @(item.GetPropertyValue<string>("propertyAlias"))
}
```
Hope this helps?

Cheers,
- Lee

okay, continuing on... i know this is programming 101, but me != developer...

how do you avoid the object not set to instance with a call like this?
```
rotLink = item.GetPropertyValue<IPublishedContent>("carouselContentLink");
```
carouselContentLink is a content picker????

Bob, I had the same problem with a Nested Content inside a DocType Grid Editor. I could get the ID using GetPropertyValue, but GetPropertyValue<IPublishedContent> returned null.

Hey Jason,

OTB NC, doesn't come with any value converters installed so to have a link node return IPublishedContent, you need to have a value converter defined that does this. The easiest way to do this for common datatypes is to install Jeavons Umbraco Core Property Value Converters package here https://our.umbraco.org/projects/developer-tools/umbraco-core-property-value-converters. This should then return you the IPublishedContent you require.

Yep, I thought I nugetted that package in, but there must have been an issue I missed. Installed it as a package and it worked great.

Sorry about that!

Thanks,
Jason
