Change DiagramCommands.SendBackward behavior

[Dario Concilio]

Hi,

I would that SendBackward command set Z-Index to penultimate item and not last one.

Moreover SendToBack decreases Z-Index but until  to penultimate item.

I would this behavior because, I have ever a rectangle called "MainContainer" that "contains" other rectangles, but actually is only showed as last one under other ones, and it has to ever last one then it has to ever lowest Z-Index.

How can I do this?

I found it.....

private void topRadDiagram_CommandExecuted(object sender, CommandRoutedEventArgs e)
{
    //Indietro
    if (e.Command.Name == "Send Backward")
    {
        foreach (RadDiagramShape item in this.topRadDiagram.SelectedItems)
        {
            if (item.ZIndex < 2)
                item.ZIndex = 2;
        }
    }

    //Secondo piano
    if (e.Command.Name == "Send To Back")
    {
        foreach (RadDiagramShape item in this.topRadDiagram.SelectedItems)
        {
            if (item.ZIndex < 2)
                item.ZIndex = 2;
        }
    }

}
