MVC 3 Razor - How to fill Html.X().MultiCombo with an enum

[Ishrath]

Hi all,

What is the best way to fill a Html.X().MultiCombo with an enum.

how do i define the store reader for an enum?

My enum looks likem this

public enum ServiceStatus
        {
            Undefined   = 1,            
            InDelivery  = 2,            
            Testing     = 3,            
            Operational = 4,            
            Degraded    = 5,
            Cancelling  = 6,
            Archived    = 7,
            InOrder     = 8
        }



UI Code 
                                  Html.X().MultiCombo()
                                    .FieldLabel("Status")
                                    .LabelAlign(LabelAlign.Top)
                                    .ID("mcbBillingStatus")
                                    .Margins("0 0 0 0")
                                    .LabelWidth(200)
                                    .Width(400)
                                    .EmptyText("--- Please Select ---")
                                    .EmptyValue("-1")
                                    .Cls("form-label")
                                                                       
                                   .Items(items =>
                                    {
                                        items.Add(new ListItem()
                                        {
                                            Text =ServiceStatus.Billing.ToString(),
                                            Value = ((int)ServiceStatus.Billing).ToString()
                                        });

                                        items.Add(new ListItem()
                                        {
                                            Text = ServiceStatus.CeasedBilling.ToString(),
                                            Value = ((int)ServiceStatus.CeasedBilling).ToString()
                                        });


                                    }));

Im not happy about the above code and how do i define the store reader for an enum

You can use the following helper method

public static ListItemCollection FromEnum(Type enumType)
        {
            ListItemCollection items = new ListItemCollection();
            foreach (var item in Enum.GetValues(enumType))
            {
                var fi = enumType.GetField(item.ToString());
                var attribute = fi.GetCustomAttributes(typeof(DescriptionAttribute), true).FirstOrDefault();
                var title = attribute == null ? item.ToString() : ((DescriptionAttribute)attribute).Description;
                var value = Convert.ChangeType(item, ((Enum)item).GetTypeCode());
                var listItem = new ListItem
                {
                    Value = value.ToString(),
                    Text = title
                };
                items.Add(listItem);
            }


            return items;
        }

In Ext.Net 2.1 you can use the following code

Html.X().ComboBox().ItemsFromEnum(typeof(MyEnum))

Thank you Vladimir

Thank you for pointing me to the right direction! ItemsFromEnum method can be used directly by basing the enum

Ext.Net 2.1 you can use the following code
Html.X().ComboBox().ItemsFromEnum(typeof(Models.Se rviceCommercialStatus)));
