Hi Doogie,

What if you do something like this:

@{   
    var caseNode = Library.NodeById(1184); 
    var catNode = Library.NodeById(2108);
    
    foreach(var category  in catNode.Children.Where("visible")){   
        <h2>@category.Name | @category.Id</h2>
            foreach(var casestudy in caseNode.Children){
                <p>@casestudy.Name</p> 
            }
    }
}     

Hope this helps,

Sorry Dennis, that just returns the entire list of case studies. 

Each casestudy has a multinode tree picker with the contents of catNode

What I wanted to do was itterate through the categories of catNode, then itterate through all the case studies that have the category id in the projectCategory property (which is the multinode tree picker that has the category selection in )

Strangley...

foreach(var casestudy in caseNode.Children.Where("projectCategory.Contains(\"2109\")" ))    

Works ( But the 2109 is one possible result of catid in the top example )

Hi Doogie,

Ah okay, Did you see the documentation for the Multi-Node-Tree-Picker. There are also an example on how to configure it and get data from it using the DynamicNode razor: http://our.umbraco.org/documentation/using-umbraco/backoffice-overview/property-editors/built-in-property-editors/Multi-Node-Tree-Picker

Here is an example from one of my project where I use the Multi-Node-Tree-Picker. In this example my propertyAlias of Multi-Node-Tree-Picker is contentElementMain. And I get the elements that are picked on the page that you are view in the browser there for Model.contentElementMain

@inherits umbraco.MacroEngines.DynamicNodeContext                                                    

@if (Model.HasValue("contentElementMain")){
     foreach (var item in Model.contentElementMain){
            var node = Library.NodeById(item.InnerText);
            @node.Name 
     }
}

Hope this helps,

Aye read, and reread that page :) this seems a particular type of cruelty I am just missing something.

Not helped by my inability to make the issue clear...

I will try and simplyfy it...

This works.

foreach(var casestudy in caseNode.Children.Where("projectCategory.Contains(\"2109\")" ))    

but instead of the number 2109 i want to replace 2109 with a variable like @catid which would hold the number 2109 in that itteration.

This for example fails

var catid = "2109" ;

foreach(var casestudy in caseNode.Children.Where("projectCategory.Contains(catid)" ))    

So I am a bit stumped. :)

Perfect.... this is the final script for anyone watching. Don't quite understand the use of the (@0) bit, but it works fine. Thanks very much Denis.

@{  

var caseNode = Library.NodeById(1184);
var catNode = Library.NodeById(2108);  }

@foreach (var category in catNode.Children.Where("visible"))

{

<h2>@category.Name</h2>

var catid = category.Id.ToString();

foreach(var casestudy in caseNode.Children.Where("projectCategory.Contains(@0)",catid))   {

<p>@casestudy.Name</p>

}

}

is working on a reply...
