Visitor Group Criteria using enum property on model

Hi.

I'm creating a criterion where I want to use a enum value as input. In order to create a dropdown to choose from I call my selection factory. But when I decorate my model property to use a selection factory, I get an error.

Following is my code.

Criterion:

public class IsUserCategoryCriterionSettings : CriterionModelBase
    {
        [Required, DojoWidget(SelectionFactoryType = typeof(EnumCategorySelectionFactory))]
        public MyEnum Category { get; set; }

        public override ICriterionModel Copy()
        {
            return ShallowCopy();
        }
    }

I get follwong error:

Try

public class IsUserCategoryCriterionSettings : CriterionModelBase
    {
        [DojoWidget(SelectionFactoryType = typeof(EnumCategorySelectionFactory))]
        [Required]        
        public MyEnum Category { get; set; }
       //or
        [DojoWidget(SelectionFactoryType = typeof(EnumSelectionFactory))]
        [Required]        
        public MyEnum Category { get; set; }

        public override ICriterionModel Copy()
        {
            return ShallowCopy();
        }
    }

Hi,

I wonder whether this might be down to the type of SelectionFactory you're using. For visitor group criteria your selection factory needs to be an implementation of EPiServer.Personalization.VisitorGroups.ISelectionFactory whereas for properties on content types, you need an instance of EPiServer.Shell.ObjectEditing.ISelectionFactory. It's also worth noting that, for visitor group criteria there's already an inbuilt Enum selection factory called EPiServer.Web.Mvc.VisitorGroups.EnumSelectionFactory which can be used like this:

[DojoWidget(
    SelectionFactoryType = typeof(EnumSelectionFactory),
    AdditionalOptions = "{ selectOnClick: true }"),
    Required]
public MyEnum Category { get; set; }

That was the issue. Thank you Paul, and the rest of you for giving valuable input :)

Try this-

public enum OrganizationTypeEnums
    {
        [Description("Internal")]
        Internal,
        [Description("External")]
        External,

    }

 public class OrgTypeSelectionFactory : ISelectionFactory
    {
        public IEnumerable<SelectListItem> GetSelectListItems(Type propertyType)
        {
            return Enum.GetNames(typeof(OrganizationTypeEnums)).ToList()
                .Select(c =>
                {
                    return new SelectListItem { Text = c, Value = c };
                });
        }
    }

public class UserTypeModel : CriterionModelBase
    {
        [DojoWidget(
         SelectionFactoryType = typeof(OrgTypeSelectionFactory),
         AdditionalOptions = "{ selectOnClick: true }"),
         Required]
        public string Type { get; set; }

        public override ICriterionModel Copy()
        {
            var model = (UserTypeModel)base.MemberwiseClone();
            model.Id = Identity.NewIdentity();
            return model;
        }
    }
