If you have upgraded from version older than Q1 2010
where we introduced our Data Source Components
, then you're probably using dataset as data source. For backwards compatibility reasons Telerik Reporting supports binding directly to IEnumberable/IListSource objects (incl. arrays, collections, DataSet, DataTable, DataView, DbDataAdapter), however you would not be able to select them as data source from the Report Designer
, and if they were selected prior the upgrade, they would still be used as data source. For version after Q1 2010 consider using the ObjectDataSource Component
that can handle this types of data sources.
All the best,
the Telerik team
