Hi,

You could do that using the HitTestHandles event:

node.HandlesStyle = HandlesStyle.Custom;
node.AnchorPattern = AnchorPattern.Decision1In3Out;
diagram.ModificationStart = ModificationStart.AutoHandles;
diagram.ShowAnchors = ShowAnchors.Always;

private void diagram_HitTestAdjustmentHandles(object sender, HitTestEventArgs e)
{
	var node = e.Item as DiagramNode;
	if (node != null && node.Bounds.Contains(e.MousePosition))
	{
		bool bOverAnchorPoint = false;
		foreach (AnchorPoint pnt in node.AnchorPattern.Points)
		{
			var transform = pnt.TransformToVisual(diagram.DocumentPlane);
			if (Utilities.Distance(transform.Transform(new Point(2, 2)), e.MousePosition) < 5)
			{
				bOverAnchorPoint = true;
				break;
			}
		}
		e.HitResult = bOverAnchorPoint? -1 : 8;
	}
} 

I hope that helps,

Hi,

I resolved the problem by doing everything on the node.

Do you see any evil on doing it this way?

   public override bool HitTestHandle(Point mousePosition, ref int hitResult)
       {
           if (Parent == null)
               return false;

           if (Bounds.Contains(mousePosition))
           {
               bool bOverAnchorPoint = false;
               foreach (AnchorPoint pnt in AnchorPattern.Points)
               {
                   var transform = pnt.TransformToVisual(Parent.DocumentPlane);
                   if (MindFusion.Utilities.Distance(transform.Transform(new Point(2, 2)), mousePosition) < 5)
                   {
                       bOverAnchorPoint = true;
                       break;
                   }
               }
               hitResult = bOverAnchorPoint ? -1 : 8;

               if (hitResult != -1)
               {
                   return true;
               }
           }
           return false;
       }

I have a problem regarding Anchor Points. I have different diagram nodes and i have set anchor points as percentage points to them to set it onto the boundaries of the node. The issue is these points behaves like absolute values when i do the scaling or resizing of the node. ie The points location does not change as the size of the Node changes.

Please tell me what could be the issue.

my code is like 
AnchorPattern anchorPattern = new AnchorPattern();
          anchorPattern.Points = inputAnchorPoints;

          foreach (AnchorPoint anchorPoint in anchorPattern.Points)
          {
              anchorPoint.MarkStyle = MarkStyle.Rectangle;
          }

          diagramNode.EnabledHandles = nodeControl.EnableHandles;
          diagramNode.AnchorPattern = anchorPattern;
