In which way is it failing? AFAIK, there is no way to know, from the text shape, if it connected to connectors. For a connector, you have StartShape and EndShape; but for the text shape you have no way to know which connectors are connecting it. One way is to track this information in a collection of connected shapes and for each connected shape store the information about its connectors. Then, when you get notified that a shape is being removed, search the shape in the collection and remove its connector. Regards -- Ariel Constenla-Haile La Plata, Argentina
