Retrieving current document fields efficiently.
What's the recommended method of retrieving custom data fields from the current document in order to minimize database calls? - CMSContext.CurrentDocument.GetValue() for each field, or use one of DocumentHelper.GetDocument(), TreeHelper.SelectSingleNode()?, or another way? If the latter, does it make sense to wrap the call in DataCacheHelper.GetCached<CMS.TreeEngine.TreeNode>?

Thanks!

Hi,

if you use CMSContext.CurrentDocument.GetValue("columnName"), the context data are selected from the cache therefore this way is effective.

DocumentHelper.GetDocument(), TreeHelper.SelectSingleNode() would select data from database.
