  Hi,

  You can extend the C1Map and override the OnMouseDown, OnMouseMove, and OnMouseUp events to detect dragging and the initial and final point. Then in MouseUp, you can add a VectorPolygon according to the points.
  
  Please refer to the sample attached that adds a rectangle to the Map if you drag Mouse while holding the Control key.

  Thanks, this is the straightforward way.
  
  I added a rubberbox for better targeting.
