DragAndDrop on Round ShapeNode

Hello!
I have MindFusion.Diagrammimg lib for WinForms (PE).
For DragAndDrop I use GetNodeAt function.
When I make drop on RectangleNode - it's ok, it's working. But when on RoundNode - GetNodeAt returns null. I have to resize to increase this node, and only after that this function return proper node.
How can it be fixed?
Thanks!

Hi,

GetNodeAt works fine for me. Are you converting the drag-and-drop position from screen to view to diagram coordinates? e.g.

PointF point = diagramView.ClientToDoc(
    diagramView.PointToClient(new Point(e.X, e.Y)));

this code I use to find node:
Point p = this.PointToClient(new Point(e.X, e.Y));


PointF targetPt = diagramViewMain.ClientToDoc(p);


DiagramNode dn = diagramMain.GetNodeAt(targetPt, true, false);

-------------------------
Thanks, your code works good!

You were using the form's PointToClient method and it works now if using DiagramView.PointToClient?

Yes.
