Hi,

Put your page content of aspx in <update panel=""> of ajax to avoid the pageload when ever you are selecting some item in the dropdown.

or

write a javascript function that will be called when the dropdown selected index changed event occurs.

function()
{
get the value selected based on the question number.
reset the dropdown.
}

Hope this helps.
