Hi all,

Using the ContentService, I found that my dropdown was returning an int instead of the actual string value entered as the prevalue.

I found this page:

https://our.umbraco.org/forum/using-umbraco-and-getting-started/76225-getting-the-correct-value-from-a-dropdown

...which is getting me closer, so I now have this code:

        var contentType = Services.ContentTypeService.GetContentType("location");
    var contents = Services.ContentService.GetContentOfContentType(contentType.Id);

    try
    {
        var locations = contents.Where(x => x.Published
        && (x.GetValue<string>("City").ToLower() == model.City.ToLower() || string.IsNullOrWhiteSpace(model.City))
        && (Services.DataTypeService.GetPreValueAsString(Convert.ToInt32(x.GetValue<string>("State"))) == model.State || string.IsNullOrWhiteSpace(model.State)))
            .Select(t => new Location
            {
                Name = t.Name,
                StreetAddress = t.GetValue<string>("StreetAddress"),
                State = umbraco.library.GetPreValueAsString(Convert.ToInt32(t.GetValue<string>("State"))),
                Postcode = t.GetValue<int>("Postcode"),
                City = t.GetValue<string>("City"),
                Phone = t.GetValue<string>("Phone"),
                Id = t.Id,
                Geolocation = JsonConvert.DeserializeObject<Geolocation>(t.GetValue("geocoder").ToString())
            }).ToList();

        return locations;
    }
    catch (Exception ex)
    {
        Logger.Error(this.GetType(), ex.Message, ex);
        throw;
    }

But I get this error:

2016-11-23 00:46:11,628 [P11604/D48/T68] ERROR LocatorApiController - Object reference not set to an instance of an object. System.NullReferenceException: Object reference not set to an instance of an object. at LocatorApiController.<>cDisplayClass2_0.0(IContent x) in C:\Repositories...\Controllers\LocatorApiController.cs:line 91 at System.Linq.Enumerable.WhereSelectEnumerableIterator`2.MoveNext() at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection) at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source) at LocatorApiController.SearchLocation(LocatorFormViewModel model) in C:\Repositories...\Controllers\LocatorApiController.cs:line 91

Not sure how to fix this?

Thanks, Chris
