I've been fighting this for a few days, and need to see if anyone has any ideas where to go with this. The code below is straight from the documentation, and works perfectly.
var faculty = Model.Content.Site().FirstChild("personnel").Children("personnelItem")
.Where(x => x.IsVisible());
@foreach(var item in faculty) {
foreach(var i in item.GetPropertyValue<IEnumerable<string>>("programList"))
{
<li>@i – @item.Name</li>
}
}
Sample result:
Welding Technology – Bob
Advanced Emergency Medical Technician – Steve
Emergency Medical Technician – Steve
Firefighter – Steve
Emergency Medical Technician – Aaron
Nail Technician – Andrea
Practical Nurse – Annie
Academic Development – Sarah
Academic Development – Brent
What I need is to be able to run GroupBy on the checkbox list values (programList). so that 'Emergency Medical Technician' is Key, with the different instructors under listed below.
I think the code below is where I need to be headed, but I can't seem to sort out how to plug my 'var faculty' into the 'List
List<string> colors = new List<string>();
colors.Add("green");
colors.Add("blue");
colors.Add("yellow");
colors.Add("green");
colors.Add("yellow");
IEnumerable<IGrouping<string, List<string>>> groupedColors =
colors.GroupBy(
c => c,
(key, result) => return new { Color = key, Count = result.Count() }
);
foreach(var group in groupedColors)
{
Console.WriteLine(string.Format("Key (Color): {0}tCount: {1}", group.Color, group.Count));
}
Anyone else attempted to do this, with success? Thanks.
I've tried to follow you along.. hopefully I've got this right. You have a list of personnel umbraco items and this contains a checkbox with the faculties?
I realise I've done this in v8 - I've tried to tweak my code accordingly but try this:
var facultiesWithUsers = new Dictionary<string, List<string>>();
var personnel = Model.Content.Site().FirstChild("personnel").Children("personnelItem")
.Where(x => x.IsVisible());
// var personnel = Model.Root().FirstChild("personnel").Children("personnelItem")
// .Where(x => x.IsVisible());
var uniqueFaculties = personnel.Select(x => x.Value<IEnumerable<string>>("faculty")).SelectMany(x => x).Distinct().ToList();
// populate the dictionary
foreach (var uniqueFaculty in uniqueFaculties)
{
var personnelInFacultyList = personnel.Where(x => x.GetPropertyValueValue<IEnumerable<string>>("faculty").ToList().Contains(uniqueFaculty)).Select(x => x.Name).ToList();
//var personnelInFacultyList = personnel.Where(x => x.Value<IEnumerable<string>>("faculty").ToList().Contains(uniqueFaculty)).Select(x => x.Name).ToList();
// add item to the dictionary with the personnel
facultiesWithUsers.Add(uniqueFaculty, personnelInFacultyList);
}
// test output
foreach (var curFacultiesWithUsers in facultiesWithUsers.OrderBy(x => x.Key))
{
<h3>@curFacultiesWithUsers.Key</h3>
<ul>
@foreach(var curUser in curFacultiesWithUsers.Value)
{
<li>@curUser</li>
}
</ul>
}
I tried to do it purely in Linq in a single query and my head hurt - hopefully this will work,
Interested to see if someone else can do it more succinctly.
Steve - thank you. Initial tests look promising, but it seems some of my data is incomplete. Once I get that sorted out, hopefully I'll be able mark as the answer.

Finally got around to testing this - results are exactly what I was after. Thank you!
Great stuff,
If it's doing hundreds of nodes and a lot of searching to find these nodes I'd recommend you put it in a partial view and cache it.
