{
    string rectString = XamlWriter.Save(rect1);

    DataObject rectangleData = new DataObject(DataFormats.Xaml, rectString);
    Clipboard.SetDataObject(rectangleData);
}

void pasteButton_Click(object sender, RoutedEventArgs e)
{
    if (inkCanvas1.CanPaste())
    {
        inkCanvas1.Paste(new Point(100, 100));
    }
}

Private Sub copyXamlButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)

    'string rectString = Parser.SaveAsXml(rect1);
    Dim rectString As String = XamlWriter.Save(rect1)

    Dim rectangleData As New DataObject(DataFormats.Xaml, rectString)
    Clipboard.SetDataObject(rectangleData)

End Sub


Private Sub pasteButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)

    If inkCanvas1.CanPaste() Then
        inkCanvas1.Paste(New Point(100, 100))
    End If

End Sub
