Make a validation group of the first dropdownlist and the Submit button.

Solution 1

On page submit, raise a JS method. In it, find the selected value of both dropdowns. If you find any one of them having value, let the page postback. If you find both of them not selected, raise an alert and cancel postback.

Try out.

Try this.
