CoreTextEditContext::SelectionRequested_revoker SelectionRequested(auto_revoke_t, TypedEventHandler<CoreTextEditContext, CoreTextSelectionRequestedEventArgs const&> const& handler) const;
public event TypedEventHandler<CoreTextEditContext,CoreTextSelectionRequestedEventArgs> SelectionRequested;
function onSelectionRequested(eventArgs) { /* Your code */ }
