Ejemplos

En el ejemplo de código siguiente se muestra un método deinvalidado WebPart.PartCommunicationInitque crea una estructura de datos CellProviderInitEventArgs para contener los valores de propiedad FieldName y FieldDisplayName , se establece los valores de propiedad y, a continuación, se desencadena el evento CellProviderInit . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz ICellProvider .

      ' Step #9: Override the PartCommunicationInit() method
      ' PartCommunicationInit() is called by the Web Part 
      ' infrastructure during the ASP.Net PreRender

      ' the other connected parts.
      ' It is important to always pass initialization information as 
      ' some parts
      ' may not behave properly if this initialization information is 
      ' not received.
