I'm sure this is a simple question but was not able to find anything on initial searching. How can I access the data values from a partial view?

When Umbraco native data types I could do something like:

// Get data type id
var dataTypeId = 1234;

var preValues = PreValues.GetPreValues(dataTypeId).Values;
var enumerator = preValues.GetEnumerator();

<div class="datatype-items">    
    <ul>
    @while (enumerator.MoveNext())
    {           
        // Get List Item Value  
        var category = ((umbraco.cms.businesslogic.datatype.PreValue)enumerator.Current).Value;

        // Output item name 
        <li>@category</li>
    }
    </ul>
</div>

Many thanks in advance!
