you can determine if radiobutton or checkbox checked radiobutton.checked property.

in case this:

private void textbox1_textchanged(object sender, eventargs e) {     if(!rbtvalorfixo.checked)       substituipontovirgula_textbox(sender textbox, e); } 

or:

private void textbox1_keypress(object sender, keypresseventargs e) {     if(rbtvalorfixo.checked)       numeropontoouvirgula_textbox(sender textbox, e);     else       formatarporcentagem_textbox(sender textbox, e); } 

and on.
