Field validation Per Submit buttuns

[Shaker]

For simplicity, I have on one form:
-textbox1/Requiere For validation1 / submitbuttun1,

-textbox2/Requiere For validation2 / submitbuttun2,

I have two submit buttons on an ASP.Net page with two textboxes and two
require for validation controls per textbox.


My concern is when button on is pressed, then validation1 is fired only,
Without validation2 and vice versa.

Is that possible, or is there any workaround to obtain this.

help.
