Identity Of Controls

i have a webpage which has 3 forms and each of the form has a about 20 controls. now what i want is to have these controls displayed in a mixed manner on the screen. moreover the ACTION pages of all the three forms are different. so is there anyway in which we can specify that TO WHICH FORM do they belong

my page is something like this

FORM1 starts
TEXTBOX(of FORM1)
FORM2 starts
TEXTBOX(of FORM2)
BUTTON(of FORM1)
END OF FORM1
TEXTBOX(of FORM2)
END OF FORM2
