    Display number of Children for a specific name Node

    Hi

    Im using this code to display the number of children underneath a specific node. At the moment it is doing so via the node's ID. Is there a way to set it so it goes off the Node's Name instead?

    code:

    var MYnode = Umbraco.TypedContent(1562); var MYchildAmount = MYnode.Children.Count();

    Currently @MYchildAmount jobs

    Thanks

    Hi Jools,

    Something like should work - you get the website root node and then work down from there:

    var siteNode = Umbraco.TypedContentAtRoot().First();
var locationsNode = siteNode.Children.Where(x => x.Name == "Locations").FirstOrDefault();
var jobs = locationsNode.Children.Where(x => x.DocumentTypeAlias == "job").Count();

    I'm guessing jobs are in a location (this might be department or whatever so change this to suit). The last like counts the jobs - if you only have jobs under these containers you could remove the where check on the docType.

    This is a simple example that does no null checking. You probably should check if the locations node exists on the count. 

        var jobs = locationsNode != null ? locationsNode.Children.Where(x => x.DocumentTypeAlias == "propertyArea").Count() : 0;

    Thanks Steve - that works great.

    Im just trying to develop it further using a loop, but being a designer my razor is very limited.

    <div class="box">
     <h2>IT Jobs</h2>
     <div class="job-info">
          <div class="count">There are currently @ITchildAmount jobs</div>
          <a href="/it-jobs/">View jobs</a>
     <div>
     <p class="no-jobs">Sorry no jobs available</p>
<div>

    So all i want to do, is if the @ITchildAmount = 0 then hide the 'job-info' div and show the 'no-jobs' div instead.

    Trying to get a for loop going but doing something wrong.

    Might you be able to point me in the right direction?

    Thanks again
