    How to get the prevalues from a dropdown

    Hello all,

    I have a dropdown datatype and I'm trying to pull all of the prevalues into my Razor page. I'm new to dotnet and everything I've tried makes my site explode. Any help would be appreciated.

    Thanks

    Hello Philip!

    I belive you could use IDataTypeValueService. Inject it into your razor view by doing this:

    @inject IDataTypeValueService _dataTypeValueService;

    Then you could use it like this:

    _dataTypeValueService.GetItemsFromValueListDataType("dataTypeAlias", null);

    I hope this helps you get on the right track!

    thank you Johannes.

    Is there a @using statement I should include? When I inject IDataTypeValueService into my razor page, it breaks with teh error: The type or namespace name 'IDataTypeService' could not be found (are you missing a using directive or an assembly reference?)

    Thanks again

    For default Umbraco I can only find details on a 'DataTypeService' not a Value service, but perhaps it's what was meant? Handy to know where this sort of thing is in the documentation either way :3 It shows the usings needed for views.

    The only mention of a DataTypeValueService I can find is a custom service in a tutorial for v8 done by Paul Seal.

    Ah! Sorry, I was a bit quick there!

    Yes!

    @using Umbraco.Cms.Core.Services;
@using Umbraco.Cms.Core.PropertyEditors;

    Then you can do

    var dataTypeConfig = (ValueListConfiguration)_dataTypeValueService.GetDataType("dataTypeName").Configuration;
