Examples

O exemplo de código a seguir mostra um método substituído PartCommunicationInit que usa a propriedade FieldDisplayList para definir os nomes de exibição do campo opcional fornecidos em uma instância da classe ListProviderInitEventArgs . 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.
            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.
                RaiseEvent ListProviderInit(Me, listProviderInitArgs)
            End If
        End Sub

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

    // Check if connected.
    if(_connected)
    {
        // If there is a listener, fire ListProviderInit event.
        if (ListProviderInit != null)
        {
            // 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);
        }
    }
}
