When a Web Parts control implements the System.Web.UI.WebControls.WebParts.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 System.Web.UI.WebControls.WebParts.RowCallback delegate represents the method to call for retrieving the provider data.

The IWebPartRow.GetRowData(RowCallback) method contains a System.Web.UI.WebControls.WebParts.RowCallback delegate parameter. The IWebPartRow.GetRowData(RowCallback) method is used in the System.Web.UI.WebControls.WebParts.RowToFieldTransformer class and the System.Web.UI.WebControls.WebParts.RowToParametersTransformer class to retrieve row data for transformation.
