Ejemplos

En el ejemplo de código siguiente se muestra un método invalidado GetInitEventArgs que devuelve una instancia de la clase InitEventArgs . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz IFilterConsumer .

' Step #8: Override the GetInitEventArgs method.
' GetInitEventArgs() is called by the Web Part infrastructure during 
' the ASP.NET PreRender event to gather the 
' necessary information it needs to build the transformer dialog. The 
' transformer dialog is needed when connecting different interfaces 
' such as IRowProvider to ICellConsumer. The transformer dialog allows 
' the user to map the fields between the interfaces. The 
' GetInitEventArgs()method only needs to be implemented for interfaces 
' that can participate in a transformer which are the following:
' ICellConsumer, IRowProvider, IFilterConsumer, IParametersOutProvider, 
' IParametersInConsumer.
' <param name="interfacename">Name of interface on which the Web Part 
' infrastructure is requesting information</param>
' <returns>An InitEventArgs object</returns>
Public Overrides Function GetInitEventArgs(interfaceName As String) As InitEventArgs
   ' Check if this is my particular cell interface.
   If interfaceName = "MyFilterConsumerInterface" Then
      'Ensure that all of the Web Part's controls are created.
      'The _filterFieldNames and _filterFieldDisplayNames are set during EnsureChildControls()
      EnsureChildControls()
          
      ' Create the FilterConsumerInitEventArgs object for the FilterConsumerInit event.
