I am not sure about your custom scenario, but if you have removed the connectors of the shapes, it is expected that an exception will be thrown. You need to have in mind that the ConnectorTool
creates connections between two points or shapes of the diagram. Since there are no connectors on the shapes, clicking on any RadDiagramShape control throws exception.
If you elaborate more on your scenario we will be able to suggest approach, achieving your requirements in another way. Sending us some clarifying pictures will be great. Could you please specify, what lines you need to draw? Can't you use the drawing tools
of the diagram?
