·         The document is for old OMS Poll Installation but it will be understandable for the new DMS as well apart from two points metioned below:

o    While adding poll control to the page presentation details add the created poll in the Datasource not as a parameter.

Sitecore RSS Feed Custom Functionality

Sometimes it is difficult to write complex xPath and sitecore Queries, to make RSS Feed work like our requirements. So, it is better to Override the Sitecore class called Sitecore.Syndication.PublicFeed.

Example

public class CustomFeed : Sitecore.Syndication.PublicFeed

    {

        public List<Item> EmbargoPressReleases = new List<Item>();

        public override IEnumerable<Sitecore.Data.Items.Item> GetSourceItems()

        {

            var Items = base.GetSourceItems();

            foreach(Item i in Items)

            {

                if(i.TemplateID == Consts.Template.PressRelease)

                {

                    if(Sitecore.DateUtil.IsoDateToDateTime(i.Fields[Consts.FieldName.PublishDate].ToString()) <= DateTime.Now)

                    {

                        EmbargoPressReleases.Add(i);

                    }

                }

            }

            return EmbargoPressReleases;

        }

    }
