Completely disable viewstate

[sri_san]

Hello,
I have a aspx page in which I would like to eliminate all of
the hidden variables as this page would be imported to an email client
and the hidden controls are usually rendered in the mail client. The
asp.net form does have the form input hidden control inspite the
viewstate is disabled at the page level. Isnt there a way to eliminate
it? And, as per my understanding, it just cant be eliminated. Now, I
was trying to parse the page treating it as a XML doc and remove the
hidden control. The problem there would be - there is no guarantee that
the XML document is well formed as the page contains formatted text and
might miss some of the closing tags. Is there a better way to get rid
of the input hidden form level viewstate ( ID = "__VIEWSTATE") ?

Thanks,
Sam.

I believe you are correct...

as you don't care about postback just add to your page:


// override standard viewstate handler with do nothing
protected override void SavePageStateToPersistenceMedium(Object state)
{
}

You'll probably run into problems trying to get a XML compliant document
from a HTML page unless you go out of your way to make the page compliant.

If you really need to eliminate the viewstate you could use a regular
expression to find and remove it.

Thanks for the reply. I would appreciate any pointers in specific the
use of regular expressions to remove it from the page.

P.S: Overriding 'SavePageStateToPersistenceMedium' clears the viewstate
completely but the hidden control is still rendered on the page.

Thanks again,
Sam.

Yes, but that still leaves the hidden controls which the OP wants removed,
for some reason...

do this using a response filter + regex
