Since Q1 2010 DataSet is no more the preferred type of data source object. Instead we have introduced the new Data Source Components
and this is the suggested way to proceed from now on. You can still use DataSet as a data source but you should create it by yourself. As you have correctly noticed the ObjectDataSource
is the way to go.
Anyway if your reports display data from a database, instead of using DataSets and DataTables we suggest using the SqlDataSource
component that is designed to work especially with Telerik's reporting engine thus offering much better performance.
