I have gotten a bit stuck here and looking for som guideance.
So I have an Neasted content data type. And I want to fetch the values in a controller.
I can fetch the first Neasted content byt doing something like this var foo = settingsNode.Properties.Where(x => x.PropertyTypeAlias == backgroundPickerAlias); and that becomes an Umbraco.Web.PublishedCache.XmlPublishedCache.XmlPublishedProperty. But I am having touble fetching the values. By doing foo .Value I get object <string>, but I can't figure out how to get the value of the object. I have been trying to do some LINQ statement, like "Select" and "Where" but it says 'object' does not contain a definition for 'Where' and the best extension method overload PublishedContentExtensions.Where(IEnumerable<IPublishedContent>, string)' requires a receiver of type 'IEnumerable<IPublishedContent>'
You can retrieve a Nested Content's property values in the format of an IEnumerable of IPublishedContent - there is an individual IPublishedContent item representing each repeating Nested Content Item.
Have a look at the reference page in the docs for some examples and explanation:
But essentially if your NestedContent Property type has alias "backgroundItems"
you would be able to get the list of repeating items like so:
var allBackgroundItems = settingsNode.GetPropertyValue<IEnumerable<IPublishedContent>>("backgroundItems");
then you could loop through each of these items and read the individual properties for each repeated element eg
@foreach (var backgroundItem in allBackgroundItems){
//use the alias of the properties of the repeating document type to read the values eg: if there were a 'title' property
var backgroundItemTitle =
backgroundItem.GetPropertyValue<string>("title");
var backgroundImage =
backgroundItem.GetPropertyValue<IPublishedContent>("backgroundImagePicker");
}
unless I've misunderstood what you are trying to do!
What I am trying to achive is to get the background Image in a Neasted Content, on the newly saved node and save that url somwhere.
So I am using theCustomApplicationEventHandler for the "on save event".
I have tried your suggested method, but I would only recive the Published content, but it's not published yet, So this would only work if I where to save and publish 2 times in a row. That's why I trying to get the value via the "Properties" value.
ahh yes, sorry I misunderstood, context is everything!
I think, if you are working with an IContent object in the Save event the value, will currently be a blob of JSON for the Nested Content property you are saving, and so you will need to deserialise it first to start reading the values:
var nestedItems = JsonConvert.DeserializeObject<List<Dictionary<string, object>>>(settingsNode.GetValue<string>("nestedContentPropertyAlias"));
then you can loop through the list of dictionary items and their values...
Neasted content value in controller
Hello Evryone!
I have gotten a bit stuck here and looking for som guideance.
