how to use more than one validation in one page

Question

I have 2 radio button (radiobtn1 and radiobtn2) in one group and 4 text box which names are a, b, c, d. And end of the page there is standard button. I add asp:requiredFieldValidators to all of textboxes. So when I clicked my button asp:validationsummary works for all of textboxes.

I want to do that if radiobtn1 was clicked, validationsummary should work for textbox a and b, if radiobtn2 was clicked, validationsummary should work for should textbox c and d.

how can I do that?

thx.
