You need to use a GoImage object as the GoLabeledLink.MidLabel. Something like:

[code] [Serializable]
public class GridViewIcon : GoImage {
public GridViewIcon() {
this.Selectable = false;
this.Name = “star.gif”;
this.Size = new SizeF(10, 10);
}

public GridViewIcon(String name) {
  this.Selectable = false;
  this.Name = name;
  this.Size = new SizeF(10, 10);
}

public override bool OnSingleClick(GoInputEventArgs evt, GoView view) {
  GoLabeledLink link = this.Parent as GoLabeledLink;
  if (link != null) {
    GoNode from = link.FromNode as GoNode;
    GoNode to = link.ToNode as GoNode;
    if (from != null && to != null) {
      MessageBox.Show("show GridView for link from: " + from.Text + " to: " + to.Text);
    }
    return true;
  } else {
    return false;
  }
}

}[/code]
Example usage:

[code] GoBasicNode n1 = new GoBasicNode();
n1.Text = “N1”;
goView1.Document.Add(n1);
GoBasicNode n2 = new GoBasicNode();
n2.Text = “N2”;
goView1.Document.Add(n2);

  GoLabeledLink link = new GoLabeledLink();
  link.ToArrow = true;
  link.FromPort = n1.Port;
  link.ToPort = n2.Port;
  link.MidLabelCentered = true;
  link.MidLabel = new GridViewIcon("star.gif");
  goView1.Document.Add(link);[/code]
