Snap to lines when aligning controls at run time

Question

I have an application in which users can move controls on a form. But they re asking me for Snap-To lines to simplify the alignment of controls. I have no idea about snep-to lines and how to implement them - I looked:

http://msdn.microsoft.com/en-us/library/ms752100.aspx Adorner's, but he talks about it only for WPF. And I tried this in WinForms, but (as expected) did not work.

How can I get binding to lines (something like VS in VS) in my application?

thank

        this.Left -= this.Left % grid;
    if (this.Top % grid != 0)
