A simple read-only Sitecore data provider with hierarchical data
This article follows on from a simple read-only Sitecore data provider.
In the previous article the external data was a simple list of objects with no hierachical structure. If, however, the external data represents a hierachical structure we need to tell Sitecore how the relationship is formed in order to enable the data provider to build the hierachical structure as an item hierarchy. To do this we need to revisit the GetChildIDs method of the data provider.
