Ayuda desesperada con Delegados

Ya hace unos días hice esta consulta, pero no he recibido respuestas y no
he
podido solucionarlo. Pongo un botón en una celda de un ListView, y
necesito
que, cuando se haga click en un botón, me informe en que row del ListView
se
ha apretado el botón.
Con este código, al presionar click, ingresa siempre en el evento normal
(no
con delegado) btn_Click, pero nunca en el que yo indico

Gracias por la ayuda
