It is clear now. I will look for a solution and get back to you soon.

I was able to achieve the desired result using custom drawing of links. First, in order to prevent the default text from appearing, either set DiagramLink.Text to an empty string or DiagramLink.TextColor to Transparent. Then set the CustomDraw property of each link to CustomDraw.Additional. Finally, handle the Diagram.DrawLink event and use the following event handler:

void diagram_DrawLink(object sender, DrawLinkEventArgs e)
{
      if (e.Shadow)
            return;
      if (e.Points.Count != 3)
            return;

      DiagramLink link = e.Link;
      string text = Convert.ToString(link.Tag);
      PointF at = e.Points[2];

      if (string.IsNullOrEmpty(text))
            return;
      if (link.Font == null)
            return;

      SizeF size = e.Graphics.MeasureString(text, link.Font);
      using (Brush textBrush = new SolidBrush(link.TextColor))
            e.Graphics.DrawString(text, link.Font, textBrush, at.X - size.Width / 2, at.Y - size.Height - 0.5f);
} 

Because the link's Text is now an empty string (to prevent its default rendering) the text of each link is supplied through the Tag parameter. In addition the event handler above expects that the link has at least three control points and renders the text above the third point.

I hope this helps.

Seems I have yet one more question.  As a designer and not a coder I'm having difficulty removing the shadow from the link text generated in the code below. I can remove the shadow from the whole diagram but that's not what I want. I'm also looking to make the text for those links bold.

Seems like no matter what I do I can't make any of the link text bold.  Here's the code so far:

[code]
       protected void DiagramView1_OnDrawLink(object sender, DrawLinkEventArgs e)
       {
           if (e.Shadow)
               return;

           DiagramLink link = e.Link;
           string text = Convert.ToString(link.Tag);
           PointF at = e.Points[2];

           if (string.IsNullOrEmpty(text))
               return;
           if (link.Font == null)
               return;
           
           SizeF size = e.Graphics.MeasureString(text, link.Font);
           using (Brush textBrush = new SolidBrush(link.TextColor))
               e.Graphics.DrawString(text, link.Font, textBrush, at.X - size.Width / 2, at.Y - size.Height - 0.5f);
       }
[/code]

Thanks in advance for the help yet again!

Thanks! That worked!
