RetrievalAttributes Property (ListData object)



A NamedValues collection for requesting attributes to be returned with data retrieval calls.  A single collection is used to specify the desired return for all points for all ListData methods retrieving data.



The object placeholder is an object expression that evaluates to a ListData object.


The RetrievalAttributes available are dependent on the Server type and version.  Requesting these attributes requires more processing and memory for each data value so consideration should be given to how much information is needed. The attributes available for request are listed in the table below. These attributes may be requested by adding any of the keywords named below to the NamedValues collection for this property or all of them may be requested by using the "All" keyword as a NamedValue with a boolean value=TRUE.
