Exemplos

O exemplo de código a seguir demonstra como usar essa propriedade para implementar o suporte de compartilhamento.

void SDKSample::WebViewControl::Scenario7::Share_Click(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
    dataTransferManager = DataTransferManager::GetForCurrentView();
    dataRequestedToken = dataTransferManager->DataRequested += ref new TypedEventHandler<DataTransferManager^, DataRequestedEventArgs^>(this, &Scenario7::dataTransferManager_DataRequested);
    DataTransferManager::ShowShareUI();
}

// Data requested handler
void SDKSample::WebViewControl::Scenario7::dataTransferManager_DataRequested(DataTransferManager^ sender, DataRequestedEventArgs^ args)
{
    DataRequest^ request = args->Request;
    DataPackage^ p = WebView7->DataTransferPackage;
    
    if (p->GetView()->Contains(StandardDataFormats::Text))
    {
        p->Properties->Title = "WebView Sharing Excerpt";
        p->Properties->Description = "This is a snippet from the content hosted in the WebView control";
        request->Data = p;
    }
    else
    {
        request->FailWithDisplayText("Nothing to share");
    }
    dataTransferManager->DataRequested -= dataRequestedToken;
}
private void Share_Click(object sender, RoutedEventArgs e)
{
    dataTransferManager = DataTransferManager.GetForCurrentView();
    dataTransferManager.DataRequested += dataTransferManager_DataRequested;
    DataTransferManager.ShowShareUI();
}

void dataTransferManager_DataRequested(DataTransferManager sender, DataRequestedEventArgs args)

    DataRequest request = args.Request;

    dataTransferManager = dataTransferManager.GetForCurrentView()
    AddHandler dataTransferManager.DataRequested, AddressOf dataTransferManager_DataRequested

End Sub

        p.Properties.Description = "This is a snippet from the content hosted in the WebView control"
        request.Data = p
    Else
        request.FailWithDisplayText("Nothing to share")
    End If
    RemoveHandler dataTransferManager.DataRequested, AddressOf dataTransferManager_DataRequested

Comentários

Normalmente, essa propriedade é usada para dar suporte ao compartilhamento. Durante uma operação de compartilhamento, o aplicativo de origem coloca os dados que estão sendo compartilhados em um objeto DataPackage e envia esse objeto para o aplicativo de destino para processamento.
