    Multi-Node Tree Picker in Partial View

    Trying to attempt to display content in a partial view though the use of the Multi-NodTree Picker (Alias homePreviewColumns)

    Issue lies in NodeById is inherted through umbraco.MacroEngines.DynamicNodeContext and as I'm in MVC mode I need to inherit from Umbraco.Web.Mvc.UmbracoTemplatePage. Please correct me if I'm wrong?

    Does anyone know of a work around?

    @using umbraco.MacroEngines
@using umbraco;
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{
    if (CurrentPage.HasProperty("homePreviewColumns"))
    {
        int[] nodeList = uQuery.GetXmlIds(CurrentPage.homePreviewColumns.ToXml());
        foreach (int preview in nodeList)
        {
            var node = Model.NodeById(preview);
            <p>@node.name</p>
        }
    }

}

    Solved!

    My solution was to create an instance of DynamicNode but could of used umbraco.NoteFactory

    @{
    int[] nodeList = uQuery.GetXmlIds(CurrentPage.homePreviewColumns.ToXml());
        foreach (int preview in nodeList)
        {
        var node = new DynamicNode(preview);
//var node = new umbraco.NodeFactory.Node(preview);  Alternative
@node.GetProperty("pageTitle").Value
@node.GetPropertyValue("pageContent")}

    I like to work with IPublishedContent so have an extension method like so (also store tree picker as csv not xml).

     

        public static IEnumerable<IPublishedContent> GetContentList(this IPublishedContent page, string alias)
    {
        return cache.Get<IEnumerable<IPublishedContent>>("GetContentList[" + page.Id + "," + alias + "]", () =>
        {
            if (!page.HasValue(alias)) return new List<IPublishedContent>();
            var ids = page.GetPropertyValue<string>(alias)
                .Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries)
                .Select(x => int.Parse(x));
            var helper = new UmbracoHelper(UmbracoContext.Current);
            return helper.TypedContent(ids).Where(x => x != null);
        }, file: UMBRACO_CONFIG);
    }

     

    then you can just use it like so

    Model.Content.GetContentList("homePreviewColumns")

    You could also extend UmbracoHelper for a similar result.

    Still need to investigate performance/details of TypedContent though and check whether the caching actually helps...
