Remarks
Data is usually sent from a provider to a consumer in a Web Parts connection. However, in some cases, a provider needs a parameter from the consumer to determine which values it should send back. The IWebPartParameters interface defines members to implement that facilitate the passing of a parameter from a consumer to a provider.
The RowToParametersTransformer class implements the IWebPartParameters interface. Transformers are used to translate data between two Web Parts controls with incompatible connection points. A RowToParametersTransformer object transforms data from a provider implementing the IWebPartRow interface when the provider needs a parameter from the consumer.
The GetParametersData method retrieves the data from the provider and provides a callback method to process the data for the consumer. The callback method can be a customized method within the consumer that sets the return values accordingly.
