    Displaying Relations using Take and HasValue

    Razor

    Hi, 

    first of all, please excuse me if I can't explain the problem clearly.  I have relations where I categories incentives on my site. I display them like below:

    <div>
    @foreach (var item in categoryPage){
    RelationType relationType = RelationType.GetByAlias("relateCategoriestoIncentive");
    Relation[] relations = Relation.GetRelations(item.Id, relationType);
    List<int> relationsIds = relations.Select(x => x.Parent.Id).ToList();
    var nodeCollection = Library.NodesById(relationsIds).OrderBy("createDate desc");

    @foreach (var incentive in nodeCollection){
        if (incentive.GetPropertyValue("incentiveRecommended") == "1") {
        <article>
            <p>@incentive.incentiveTitle</p>
        </article>
        }
    }
</div>

     

    The problem is I can't apply Take(10) method in the right order. What I want to do is: 

    1- sort all incetives by createDate
    2- filter the ones that HasValue "incentiveRecommended"
    3- and Take only 10 from out of these

    I can't do the second step, since I have limited coding knowledge. I would be glad if you could guide me through
