Re: Invalid postback or callback argument. Event validation

On Aug 20, 8:20 pm, bruce barker
<brucebar...@discussions.microsoft.comwrote:
you proably have autopostback set on the dropdown (a poor coding practice).
when the dropdown is selected, it starts a postback, sending partial data as
not all the form fields (and some hidden) have been added to the dom.

the fix, is to render all the autopostback control as disabled, then in
javascript enable them after html parse has completed.
You are absolutely correct that I have autopostback enabled on the
control. Can you provide some additional information on why this is
considered a poor coding practice? I did some searching for articles
that could provide some more insight on why autopostback should not be
used and really did not find anything.

Also, do you have an example on how to enable/disable autopostback via
javascript?

THanks
