Ejemplos

En el ejemplo de código siguiente se muestra un método invalidado WebPart.PartCommunicationMain que crea un objeto RowReadyEventArgs , se establece los valores de fila y el estado de selección y, a continuación, se desencadena el evento RowReady . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz IRowProvider .

        // 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(_connected)
            {
                //If there is a listener, fire the RowReady event.

                    // RowReady event.
