RowReadyEventArgs class

NOTE: This API is now obsolete.

Provides the current row value from a Web Part that implements the IRowProvider interface when the RowReady event occurs.

public class RowReadyEventArgs : EventArgs

The following code example shows an overridden WebPart.PartCommunicationMain method that creates a RowReadyEventArgs object, sets the row values and selection status, and then fires the RowReady event. This code example is part of a larger example provided for the IRowProvider interface.

        // Step #8: Override the PartCommunicationMain method.
        // The PartCommunicationMain method is called by the Web Part 
        // infrastructure on the client during the 
        // ASP.NET PreRender event to allow the part to pass its 
        // primary data to the other connected parts.
        // It is important to always fire the RowReady event. Some 
        // parts may not behave properly if they are left waiting for 
        // this information.
        public override void PartCommunicationMain()
            // Check if connected.
                //If there is a listener, fire the RowReady event.
                if (RowReady != null)
                    // Create the RowReadyEventArgs object for the 
                    // RowReady event.
                    RowReadyEventArgs rowReadyEventArgs = new RowReadyEventArgs();

                    // Declare data variables.
                    string selectionStatus = "";
                    DataRow[] dr = new DataRow[1];

                    // If a row is selected, send the row.
                    if ( _dataGrid.SelectedIndex > -1)
                        // Generate an array containing the selected 
                        // DataRow(s).
                        dr[0] = ((DataTable)_dataGrid.DataSource).Rows[_dataGrid.SelectedIndex];
                        // Set the selection status.
                        selectionStatus = "Standard";

                        // The user hasn't selected a row so send null.
                        dr[0] = null;

                        // Set the selection status.
                        selectionStatus = "None";

                    // Set values
                    rowReadyEventArgs.Rows = dr;
                    rowReadyEventArgs.SelectionStatus = selectionStatus;

                    // Fire the RowReady event.
                    RowReady(this, rowReadyEventArgs);
