You can work around many of these rules by handling ObjectDataSource events and writing custom code.
Each record should be a custom object that exposes all its data through public properties. The query results are several records, which can be represented as a collection, an array, or a list object that implements IEnumerable. It must provide the query results when a single method is called. (If you want to use different classes for selecting and updating your data, you ll need to wrap them in another higher-level class.) None of the linked methods (for selecting or updating records) can be static. All the logic must be contained in a single class. It must have a default, no-argument constructor. That s because the ObjectDataSource will create an instance only when needed and destroy it at the end of every request. However, to use it, your data access class must conform to a few rules: It must be stateless.
The ObjectDataSource is remarkably flexible and can work with a variety of different components. The ObjectDataSource allows you to create a declarative link between your web-page controls and a data access component that queries and updates data.
