Ejemplos

En el ejemplo de código siguiente se muestra un métodoreemplazado PartCommunicationMainque crea una instancia de la clase ParametersInReadyEventArgs para enviar cuando se produce el evento ParametersInReady . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz IParametersInProvider .

      ' Step #7: Implement 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 either the ParametersInReady or 
      ' the NoParametersIn event. Some parts
      ' may not behave properly if they are left waiting for this 
      ' information.
      ' ParametersInReady should be fired to send the parameters.
      ' NoParametersIn should be fired to indicate that there is no 
      ' change in the parameters.
