Dropdown list multiple

Using Umbraco And Getting Started

Umbraco 7
Hi all,

I'm trying to loop through a multiple list dropdown and I'm having issues.

Everywhere online states that the returned value is a comma-separated list so I assumed a string would be returned which I could then loop through using a .Split(',') but this doesn't seem to work.

If i do this i get the following outputs:

System.Linq.Enumerable+WhereSelectArrayIterator`2[System.String System.String]

I have followed the tutorial on http://www.computermagic.gr/tutorials/umbraco-7/property-editors/dropdown-list-multiple/

Here is the code i have:
```
var test = item.GetPropertyValue<string>("ringCategory");
foreach (var cat in test.Split(','))
{
    <p>@cat</p>
}
```
I have also tried casting the item to an array thinking this may be an issue by both declaring the item as a

Any help?!

Hi Lewis,

Can you try to use something like this:

@{
  if (Model.Content.HasValue("ringCategory")){                                                     
       <ul>                                                        
      @foreach(var item in Model.Content.GetPropertyValue<string>("ringCategory").Split(',')) { 
        <li>@item.Name</li>
      }
    </ul>                                                                                       
  }
}

Please keep in mind that you change it so it match your case.

Hope this helps,

/Dennis

What version of Umbraco are you using?

In theory you should be able to just do this:
```
var values = GetPropertyValue<IEnumerable<string>>("ringCategory");
```
This returns an array of strings.

However, when I tried this in Umbraco 7.9.2 the collection was always empty. I think there must be a bug in this version.

If you check your umbraco.config file in /App_Data/ can you see your ringCategory property on any of your documents?

Thanks Dan! I'm in 7.12.1 and it works as you described.

if (Model.Content.HasValue("filterVals"))
{
    var filterValues = Model.Content.GetPropertyValue<IEnumerable<string>>("filterVals");
    if(filterValues != null && filterValues.Any())
    {
        foreach(var item in filterValues)
        { 
            <dd class="label-sm">@item</dd>
        }
    }
}
