How to retrieve the value from nested content inside Umbraco Grid using LeBlender editor

Question

I'm trying to retrieve the values from a nested content property editor inside a LeBlender Editor.

This is my current code:

@inherits UmbracoViewPage<Lecoati.LeBlender.Extension.Models.LeBlenderModel>

@foreach (var item in Model.Items)
    {       

  var listitems = item.GetValue("checkpointlist"); 

  <p>@listitems</p>

}

This outputs:

System.Collections.Generic.List`1[Umbraco.Core.Models.IPublishedContent]

I'm very new to C# and Umbraco, but how do I manage to output the value of the list / my nested content?

Answer 1

item.GetValue("checkpointlist") returns a list of IPublishedContent items, you can loop through this with another foreach loop. The example belows outputs the name of the items in the list. If you want to output a specific property, you can replace .Name by .GetPropertyValue("name_of_the_property")

@inherits UmbracoViewPage<Lecoati.LeBlender.Extension.Models.LeBlenderModel>
@foreach (var item in Model.Items)
{       
    var listitems = item.GetValue<List<IPublishedContent>>("checkpointlist"); 
    foreach (var listitem in listitems)
    {  
        <p>@listitem.Name</p>
    }
}
