I want to obtain a ShapeNode under the cursor when the mouse hovers over it. The following code doesn't work for me (hoveredNode is null).

diagramView1.MouseHover += new System.EventHandler(diagramView1_MouseHover);

private void diagramView1_MouseHover(object sender, EventArgs e)
{
   Point clientPoint = Control.MousePosition;
   PointF documentPoint = diagramView1.ClientToDoc(clientPoint);
   DiagramNode hoveredNode = diagram1.GetNodeAt(documentPoint, false, false);
   if (hoveredNode is ShapeNode)
   {
      Console.WriteLine("...");
    }
}
