Examples

O exemplo de código a seguir mostra um método substituído WebPart.PartCommunicationInit que cria uma instância da classe ListProviderInitEventArgs para enviar quando ocorre o evento ListProviderInit . Este exemplo de código é parte de um exemplo maior fornecido para a interface IListProvider .

 ' Step #7: Override PartCommunicationInit method.
' PartCommunicationInit() is called by the Web Part infrastructure during the ASP.NET PreRender 
' event to allow the part to pass initialization information to the other connected parts.
' It is important to always pass initialization information. Some parts
' may not behave properly if this initialization information is not received.
Public Overrides Sub PartCommunicationInit()
   ' Ensure that all of the Web Part's controls are created.
   

   ' Ensure that all of the Web Part's controls are created.
   EnsureChildControls()
   
   ' Check if connected.
   If _connected Then

         'Create the ListProviderInitEventArgs object for the ListProviderInit event.
         Dim listProviderInitArgs As New ListProviderInitEventArgs()
         
         ' Set the list field names.
         listProviderInitArgs.FieldList = _listFieldNames
         listProviderInitArgs.FieldDisplayList = _listFieldDisplayNames
         
         ' Fire the ListProviderInit event.
          ListProviderInit(Me, listProviderInitArgs)

   End If
End Sub 'PartCommunicationInit
// Step #7: Override PartCommunicationInit method.
// PartCommunicationInit() is called by the Web Part infrastructure during the ASP.NET PreRender

public override void PartCommunicationInit()
{
    // Ensure that all of the Web Part's controls are created.
    EnsureChildControls();

    // Check if connected.
    if(_connected)
    {
       
            //Create the ListProviderInitEventArgs object for the ListProviderInit event.
            ListProviderInitEventArgs listProviderInitArgs = new ListProviderInitEventArgs();
    
            // Set the list field names.
            listProviderInitArgs.FieldList = _listFieldNames;
            listProviderInitArgs.FieldDisplayList = _listFieldDisplayNames;

            // Fire the ListProviderInit event.
            ListProviderInit(this, listProviderInitArgs);
