Disable ViewState

[MCM]

I am trying to disable ViewState at the application level. I have the
following line in my web.config:

<pages enableViewState="false"></pages>

But it is not working. What can I do?

Hi MCM,

As for "disabling" ViewState, you can set "ViewState" at several different
levels:

* at web.config <pages> level
* at @page directive level, this can override the web.config level
* at control's level, this rely on whether the page's viewstate is enabled.

As for the problem behavior you encountered, how did you get that the
ViewState is not disabled? I've performed a simple test as below

*disable viewstate at web.config <pages> level

* create a new page and put a Label on the page

I can find that the Label's ViewState is not available.

Sincerely,

Steven Cheng

When I view the source of the page output, there is still a hidden field
being generated for ViewState and it does not have an empty value.

Thanks for your reply MCM,

As for the hidden "__VIEWSTATE" html hidden field, it is the expected
behavior that ASP.NET page still output it even if you disable viewstate.
This is because this hidden field is not only used for storing page or
control's ViewState data. It also contains some data for identifying the
current status(such as status between multiple postback) so that the
server-side can differenitate each request from the client-side for the
same page.
