    Nested Content GetPropertyValue

    Templates, (partial) views and macros
    Umbraco 7

    Hey,

    I'm trying to output some content from my nested content item.

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using Umbraco.Web.Models

var anchors = Model.GetPropertyValue<IEnumerable<IPublishedContent>>("anchor");
<ul>
    foreach(var anchor in anchors) {
        <li><a href="#">@anchor.GetPropertyValue<String>("anchor")))</a></li>
    }
</ul>

    But i'm getting an error saying that the render model doesn't has "GetPropertyValue" ?

    Hi Thomas It was great to meet you in person at CodeGarden.

    I think you might be missing this reference

    @using Umbraco.Web

    Try adding that at the top.

    Cheers

    Paul

    Hi Paul.

    Likewise ! :), thanks for the snaps shot.

    I tried to add that, but it's not changing anything.

    Hey Thomas,

    The issue is the point at which you are calling GetPropertyValue.

    Based on the code above, your view is inheriting from UmbracoTemplatePage.

    So, in this scenario, you need to change your third line from:

    var anchors = Model.GetPropertyValue<IEnumerable<IPublishedContent>>("anchor");

    to

    var anchors = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("anchor");

    Alternatively, you can change your 1st line from:

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage

    to

    @inherits Umbraco.Web.Mvc.UmbracoViewPage

    UmbracoTemplatePage wraps your actual Model in a Render Model, so it's exposed via the Model.Content property, where as UmbracoViewPage doesn't.

    It's becoming considered best practice to use UmbracoViewPage instead of UmbracoTemplatePage so I'd switch to that if I were you :-)

    Thanks,

    Nik

    Well spotted @nik

    @thomas I used Nested Content in my starter kit for the Main Carousel.

    I put the carousel in a partial view. Here is a link to that partial view, maybe it will help with any other things which come up.

    https://github.com/prjseal/CodeShareUmbracoStarterKit/blob/master/src/CSUSK.Web/Views/Partials/Content/_MainCarousel.cshtml

    Cheers

    Hey, Thanks guys.

    I have tried this. But are still getting the same issue.

    @inherits UmbracoViewPage
@using Umbraco.Web.Models
var anchors = Model.GetPropertyValue<IEnumerable<IPublishedContent>>("anchor");

<ul>
foreach(var item in anchors) {
  <li><a href="">@item.GetPropertyValue<string>("anchor")</a></li>
    }
</ul>

    I also tried.

     @inherits UmbracoViewPage
 @using Umbraco.Web.Models
 IEnumerable<IPublishedContent> anchors = Umbraco.AssignedContentItem.GetPropertyValue<IEnumerable<IPublishedContent>>("anchor");
<ul>
foreach (IPublishedContent item in anchors ) {
    item.GetPropertyValue<string>("anchor")
}

    Still same issue.. ?

    Hi Thomas,

    That seems odd. Both of those fundamentally look like they should work.

    Are you sure the error is still being thrown in the same view and not now being thrown in a different one?

    The top option is the one that I would go for rather than the second one.

    I'm creating an grid item with the Doc type grid editor. Does that make any changes ?
