The data to retrieve from the provider.

When a Web Parts control implements the IWebPartRow interface and serves as a provider in a Web Parts connection, the connection or transformer must retrieve the row data from the provider. The RowCallback delegate represents the method to call for retrieving the provider data.

The GetRowData method contains a RowCallback delegate parameter. The GetRowData method is used in the RowToFieldTransformer class and the RowToParametersTransformer class to retrieve row data for transformation.
