Cant get members MNTP values

I am realy stuck with this for days... I am trying to get a list of members with their Multinode tree picker values. This is my code:

   var member = Services.MemberService.GetAllMembers();

@foreach (var item in member)
{
        var typedMultiNodeTreePicker = Model.Value<IEnumerable<IPublishedContent>>("categoryPicker");
        foreach (var category in typedMultiNodeTreePicker)
        {
            <p>@category.Name</p>
        }

    <p>@item.Email</p>

}

But i am getting this error: enter image description here

Hi Silvija!

Is it the member that has the Multinode treepicker? in that case

Try changing :

var typedMultiNodeTreePicker = Model.Value<IEnumerable<IPublishedContent>>("categoryPicker");

To:

var typedMultiNodeTreePicker = item.Value<IEnumerable<IPublishedContent>>("categoryPicker");

Let me know if it works!

Hi Johannes,

Yes, its MNTP member custom property. When I try your suggestion i am getting this compilation error: enter image description here

I belive it should be

var typedMultiNodeTreePicker = item.GetProperty<IEnumerable<IPublishedContent>>("categoryPicker");

Since we want to the members property we have to use "item". Since Model is "Currentpage" and the "Currentpage" dosen't have the property value "categoryPicker"

I tried that too but i am getting this message:

enter image description here

Probably i am missing namespace , but i dont know which one. This is what i have now:

@inherits Umbraco.Web.Mvc.UmbracoViewPage

@using ContentModels = Umbraco.Web.PublishedModels;

I have done some testing of this myself, I the closest that I have gotten it this.

var typedMultiNodeTreePicker = member.GetValue<IEnumerable<IPublishedContent>>("categoryPicker");

But this returns null, but maybe it will work for you?

Otherwise I am unfortunately out of idéa :(

When I try it that way i am getting this: enter image description here

It says:

Severity Code Description Project File Line Suppression State Error CS1929 'IEnumerable

I alredy tried this before but with no luck.

Still thank you Johannes for the effort.

I'm still struggling with this. This is the closest I came to:

@{
    var member = Services.MemberService.GetAllMembers();
}

@foreach (var item in member)
{

    var typedMultiNodeTreePicker = item.GetValue<IEnumerable<IPublishedContent>>("categoryPicker");
    if (typedMultiNodeTreePicker != null)
    {
        foreach (var category in typedMultiNodeTreePicker)
        {
            <p>@category.Name</p>

        }
    }
    @item.Name
    @item.GetValue("phoneNumber")
}

Anybody else have any idea? I really got stuck. Thanks

Okay, so it looks like PropertyValueConverters don't kick in on Members.

The MultiNodeTreePicker is storing the selection as a string of UDI's separated by a comma.

So you'll have to split the string on the comma and then loop around each entry and then retrieve the IPublishedContent for the categories you are trying to retrieve.

I think "something" like this but there will be errors in my code

var categoriesString = item.GetValue<string>("categoryPicker");
foreach(var categoryString in categoriesString.Split(','))
{
    var category = Umbraco.Content(categoryString);
}

Additional Info - Untested

I think part of the issue is how you are getting the Members, if you were getting individual Members using the MembershipHelper they come back as IPublishedContent entries, in which case I suspect the PropertyValueConverters would kick in and what you were trying would work.

Hi Nik,

Thank you so much for this input. I made some progress, but forgive me if I did not correctly implement your solution.

This is my code right now:

@foreach (var item in member)
{
    var typedMultiNodeTreePicker = item.GetValue<string>("categoryPicker");
    if (typedMultiNodeTreePicker != null)
    {
        foreach (var category in typedMultiNodeTreePicker.Split(','))
        {
            <p>@category</p>
        }
    }

This is the result of it:

umb://document/7bf41d847bbe45188dc9b61b406e3445

umb://document/0a19cdbaa84b442c9fb7db33b6f5ccc5

umb://document/7656d5ad68cb4720b221854e1ddf6164

I have guids here after document/ , now i need to cut this guid and convert it , or something like that.

After hours of torture, finaly i found the solution.

    @foreach (var item in member)
{  
    var typedMultiNodeTreePicker = item.GetValue<string>("categoryPicker");
    if (typedMultiNodeTreePicker != null)
    {
        foreach (var udi in typedMultiNodeTreePicker.Split(','))
        {
            var categories = Umbraco.Content(Udi.Parse(udi)).DescendantsOrSelf()
                                             .Where(x => x.IsVisible()).ToArray(); ;

            foreach (var category in categories)
            {
                    <a  href="@category.Url">@category.Name</a><br />
             }
        }    
    }
    @item.Name <br />
    @item.GetValue("phoneNumber") <br />
    @item.Email
}

I'm sure this is not the best solution so if someone has some suggestion for improvement please suggest it here :)

Thanks
