Programmatically Get Datasource Items of a Sitecore Item

If you need to get the datasource item’s of a particular Sitecore item, we can write a few extension methods to help us out!

[code language=”csharp”]
public static class ItemExtensions
{
public static RenderingReference[] GetRenderingReferences(this Item i)
{
if (i == null)
{
return new RenderingReference[0];
}
return i.Visualization.GetRenderings(Sitecore.Context.Device, false);
}

public static List<Item> GetDataSourceItems(this Item i)
{
List<Item> list = new List<Item>();
foreach (RenderingReference reference in i.GetRenderingReferences())
{
Item dataSourceItem = reference.GetDataSourceItem();
if (dataSourceItem != null)
{
list.Add(dataSourceItem);
}
}
return list;
}

public static Item GetDataSourceItem(this RenderingReference reference)
{
if (reference != null)
{
return GetDataSourceItem(reference.Settings.DataSource, reference.Database);
}
return null;
}

private static Item GetDataSourceItem(string id, Database db)
{
Guid itemId;
return Guid.TryParse(id, out itemId)
? db.GetItem(new ID(itemId))
: db.GetItem(id);
}
}
[/code]

From here, we can write some nice code like this:

[code language=”csharp”]
foreach (Item dataSourceItem in Sitecore.Context.Item.GetDataSourceItems())
{
// do something
}
[/code]
