The following table provides the related sets of properties of the Sql Data Source control, which provides the programming interface of the control: The Object Data Source Control enables user-defined classes to associate the output of their methods to data bound controls.
The programming interface of this class is almost same as the Sql Data Source control.
Each data source control wraps a particular data provider-relational databases, XML documents, or custom classes and helps in: There are many data source controls available in ASP.
