Displaying multinode picker within list of members

Using Umbraco And Getting Started

Umbraco 7
Hi Folks,

I've got a multinode picker as a custom data type within a member - I can't pull back the data to the front end as a list.
```
@foreach (var member in ApplicationContext.Current.Services.MemberService.GetAllMembers().OrderBy(member => member.Name))

{
            <tr> 

                <td>@member.Name </td> 
                <td>@member.Email</td> 
                <td>@member.GetValue("TownCity")</td>
                <td>@member.GetPropertyValue<IPublishedContent>("Pharmacy")</td>

            </tr> 

        }
```
I would think the last row should work but it's throwing an error - Compiler Error Message: CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments

Not tried this before, so I'm a bit stuck. Any ideas will be greatly appreciated.

Cheers Darren

Hi Darren,

When you say the last line, do you mean:
```
<td>@member.GetPropertyValue<IPublishedContent>("Pharmacy")</td>
```
If so, is there a Property on the MemberDocType named "Pharmacy" and is it a node?

Thanks

Hi Craig,

Thanks for getting back to me - that's the correct line. There's a multi node picker on the MemberDocType called Pharmacy.

Cheers Darren

Hi Darren,

You should be able to do something like below:
```
var selectedPharmacy = member.GetPropertyValue<IEnumerable<IPublishedContent>>("pharmacy");
```
This should return a list of selected IPublishedContent objects.

Thanks

Dead topic, but this is the closest i could find to my problem.
```
     var listOfTradesmen = listOfMembers.Where(tradesman => tradesman.ContentType.Alias.Equals("tradesmanMember") && tradesman.GetValue<IEnumerable<IPublishedContent>>("services").Select(service => service.Id).Intersect(categoryServicesAsListOfIds).Any());
```
I have an MNTP as a field for Members, and by looking at the ModelsBuilder generated code of my member type, I did exactly the same code you suggested Darren, but alas I get a 'Value cannot be null' exception.

The field names match, and if I remove the IEnumerable return type so that I let the method decide what to return back, it returns back a stringified list of UDIs, which only complicates fitlering and searching of members now.

By any chance, do you know if I can simplify or make minimal changes to my code so that I do not need to mess around with UDIs, convert to GUID, look them up, etc etc. ? The process seems unnecessarily complicated now.

Hi Silvija,

My solution was to go along with the UDIs.

I had made a helper class containing 2 methods, one to look up the UDI as a typed content and the other to read a list of them.

public static IPublishedContent GetPublishedContentByUdi(string udi)
    {
        var umbracoHelper = new UmbracoHelper(UmbracoContext.Current);

        return udi.IfNotNull(x => umbracoHelper.TypedContent(x)) ?? default(IPublishedContent);
    }

/// <summary>
    /// Takes a stringified list of UDIs to return as IEnumerable of type IPublishedContent
    /// </summary>
    /// <param name="udi"></param>
    /// <returns></returns>
    public static IEnumerable<IPublishedContent> GetPublishedContentByListOfUdis(object udi)
    {
        return udi
            .IfNotNull(x => x
                .ToString()
                    .Split(',')
                        .Select(GetPublishedContentByUdi)) ?? Enumerable.Empty<IPublishedContent>();
    }

In the end, my code for my scenario from my previous post came to look like so (the name of my helper is PublishedContentHelper):

var allTradesmen = ApplicationContext.Current.Services.MemberService
            .GetAllMembers()
            .Where(tradesman => tradesman.ContentType.Alias.Equals(ConstantValues.TradesmanMemberTypeAlias))
            .Where(tradesman =>
                filterModel.ListOfSubscriptionOptions
                    .Select(x => x.Id)
                    .Intersect(
                        PublishedContentHelper.GetPublishedContentByListOfUdis(
                                tradesman.GetValue(ConstantValues.Tradesman_Member_Field_Subscription)
                                )
                                    .Select(subId => subId.Id))
                                    .Any()
            )
            .ToList();
