    Datatype prevalues in Umbraco 8

    Hey! I need to get the prevalues of a Data Type on my hompage. I´m using Umbraco 8. This is my master-head:

        @inherits Umbraco.Web.Mvc.UmbracoViewPage 
        @{
            Layout = null;
         }
    

    and this is my homepage-head:

    @inherits Umbraco.Web.Mvc.UmbracoViewPage<ContentModels.Homepage>
    @using ContentModels = Umbraco.Web.PublishedModels;
    
    @{
        Layout = "master.cshtml";
    }
    

    When I use

    @foreach (var categoryPrevalue in ApplicationContext.Services.DataTypeService.GetPreValuesByDataTypeId(1125).ToList())
    {
     <li>@categoryPrevalue</li>
    }
    

    I get the error:

    CS0103: The name 'ApplicationContext' does not exist in the current context

    What can I do?! Thanks and best regards, Christoph

    Try using

    Current.Services.
    

    to find the relevant service.

    Kind regards

    If I try this in a partial view it says "The name 'Current' does not exist in the current context."

    I was able to get to the DataTypeService by using Services.DataTypeService in Umbraco 8.4.1

    Hi, we created the following, to return the prevalues as a list:

    public static List<PreValue> GetDataTypePreValues(int id)
            {
                IDataTypeService dataTypeService = Current.Services.DataTypeService;
    
                List<PreValue> toReturn = new List<PreValue>();
    
                IDataType dataType = dataTypeService.GetDataType(id);
    
                if (dataType != null)
                {
                    ValueListConfiguration valueList = (ValueListConfiguration)dataType.Configuration;
    
                    if (valueList != null && valueList.Items != null && valueList.Items.Any())
                    {
                        toReturn.AddRange(valueList.Items.Select(s => new PreValue
                        {
                            Id = s.Id,
                            Value = s.Value
                        }));
                    }
                }
    
                return toReturn;
            }
    

    using the following class:

    public class PreValue
    {
            public int Id { get; set; }
    
            public string Value { get; set; }
    }
