Friday Gotcha: Sitecore.Data.Items.Item.Fields

For the sake of performance, Sitecore will not give you all fields in the FieldCollection in the following code, only fields with explicit values on item level, including empty string:

foreach(Sitecore.Data.Fields.Field field in Sitecore.Context.Item.Fields)

{

  // here you will see only fields with values (even empty string) set on item level

  // fields with null in them or standard values will not be here.

}

However, you will be able to access fields with either Sitecore.Context.Item.Fields["title"] or with a PageEditor enabled Web Control such as sc:text: <sc:text field="title" runat="server" />

In order to have all the fields in the FieldCollection and iterate through them, make sure your code will include Sitecore.Data.Items.Item.Fields.ReadAll() call before your foreach:

Sitecore.Context.Item.Fields.ReadAll();

foreach(Sitecore.Data.Fields.Field field in Sitecore.Context.Item.Fields)

{

  // do your thing here

}
