    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

    Paul

    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; }
}
