i have a dropdown control with autopostback=on that when selected,
posts back and populates a second dropdown. the 2nd dropdown takes a
while to load, giving the user time to start typing in other fields
before the screen refreshes. i would like to disable any user input
during this time, and possibly even display a "please wait" message.
is there any way to insert some client side javascript that would fire
before the postback, that would disable the user from typing or
display a wait message ?
thanks!
