access a form's method from another form

hi,

i have a form which which loads some records in a grid view and a method which refresh these records. this form is called with the new operator each time.

i want to get from another form this refreshing method, how can i? i tried

form1.method_name()

but there is no effect as there can be opened more than one instance of form1 and the compilator dosen't know which form's method to access.

i would appreciate a lot any kind of help
