Hey

i am using couple of update panels in a complex dashboard...
Now my update panel updated a list of users (who's online who's offline) in every 5 seconds, on the firebug trace i found the update panel sending 30KB of request and response.

When traced further i found that its attaching all the viewstates with it in both request and response body.

This behavior doesn’t happen if we use raw ajax via jquery.
I found via googling that its a dirty secret of ASP.NET Update Panel transmits all other data and viewstates in its callback..

Any ideas to get rid of the viewstates ?????

Thanks

If you don't want to use viewstate turn it off. Either using a page directive

<@page EnableViewState="false" ...>

or on the control(s)

<asp:updatepanel enableviewstate="false" ...>

Keep in mind though disabling viewstate has ramifications also, such as the state of controls not being maintained, like list selection, checkbox status.="

na na i want to use them for other purposes... i just want some way to override the update panel call and remove unnesessary data going with it...
moreover disabling viewstate on update panel dosent make much diff.. its all other data and viewstates of the page that goes with the call back

It is rather unseemly to add a solution to your own question and select it as the answer
