    Hi Gayathri

    What type of "promo" property? CurrentPage.GetPropertyValue("promo") returns object, you can't loop through object.

    Thanks,

    Alex

    In Umbraco 7.5 you can do

    foreach (var item in CurrentPage.Promo)
{
  @item.Alias
}

    CurrentPage.Promo should return a dynamic type, which can be looped through. Just be careful because it'll be easy to run into errors.

    Not tried this method in 7.6

    foreach (var item in CurrentPage.Promo) { @item.Alias }

    This solution throws an error

    : Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'char' does not contain a definition for 'Alias'

    Weird, it thinks that the promo value is a string and for each iteration it's using the next char.

    Anyway, have you tried using Json.Decode() ? This will convert an object which is JSON into a dynamic which can be looped
