and have put breakpoint on button click of btnproibirtp , verify , works , think u had tags formation error or :

 protected void btnproibirtp_click(object sender, eventargs e)     {         string lbl1 = lbproibidotp.selectedvalue;     }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -
