IXRScrollViewer::AddScrollChangedEventHandler (Windows Embedded CE 6.0)

This method attaches a delegate to the ScrollChanged event for this scroll viewer. When the scroll viewer raises the ScrollChanged event, this delegate will be invoked.

    IXRDelegate<XRScrollChangedEventArgs>* pDelegate
) = 0;

Parameters

• pDelegate

  The CreateDelegate helper function creates this IXRDelegate object.

Return Value
