I want to know the drop position of a library shape to create a new shape at the same place
I tried this code using mouseInDevice but the shape result out to the drawing view
Any help thanks

void EventSinkService_NodeInserted(NChildNodeEventArgs args) {
try {
if (args.Child is NErmShape) {
NErmShape nErmShape = (NErmShape)args.Child;

NPointF mouseInDevice = nDrawingView1.GetMousePositionInDevice();

if (wizExcelForm.newqwMapping != null) {
wizExcelForm.newqwMapping.X = mouseInDevice.X ;
wizExcelForm.newqwMapping.Y = mouseInDevice.Y ;
wizExcelForm.newqwMapping.CustomLocation = true;
Program.EcoSpace.UpdateDatabase();
DrawShema();
}
}
} finally {
wizExcelForm.Close();
}

} else if (nErmShape.Tag == "oledb") {
}
}
} catch (Exception ex) {
QwUtils.MessageError(ex, "EventSinkService_NodeInserted");
} finally {
}
}
