Примеры

В следующем примере кода показан метод переопределения PartCommunicationInit , который создает экземпляр класса ParametersInConsumerInitEventArgs и определяет параметр значения путем создания экземпляра класса ParameterInProperty . Данный пример кода является частью большего примера, приведенного для интерфейса IParametersInConsumer .

// Step #7: Override the PartCommunicationInit method.
// The PartCommunicationInit method 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 all controls have been created.
    EnsureChildControls();

    // Check if connected.
    if(_connected)
