Hi.

I created my own PreValueSource for the drop-down list, but I want to update this data every time the user opens the page.

 public class SportsPreValueSourceType : FieldPreValueSourceType
{
    public SportsPreValueSourceType()
    {
        Id = new Guid("104def6e-75d5-4e41-bdba-8a4983fa4a8f");
        Name = "Sports list";
        Description = "List of the sports that depends on member";
    }
    public override List<PreValue> GetPreValues(Field field, Form form)
    {
        var helper = Umbraco.Web.Composing.Current.UmbracoHelper;
        var randomValue = new Random().Next(0, 1000);

        var preValue = randomValue > 500 ? ">500" : "<500";

        return new List<PreValue>() { new PreValue() { Id = 0, SortOrder = 0, Value = preValue } };
    }

    public override List<Exception> ValidateSettings()
    {
        var exs = new List<Exception>();

        return exs;
    }
}

How I can do that?
