RadSessionPageStateCompression Not Working?

[Valery]

Hi there,

I have followed the RadCompression instructions for enabling the RadSessionPageStateCompression. Everything worked like charm in Q3 2009 but it stopped in Q1 2010. I can see a huge view state in my page and I have no idea what I did wrong.

So what are the possible reason for silently not using the RadSessionPageStateCompression adapter?

Thank you in advance,
Valery.

Hi Valery,

I'm afraid that I'm not able to observe the behavior you have described. I have attached a small test page, please take a look, maybe I'm missing something obvious.
Also you should have in mind that by default SessionPageStatePersister (used internally by our state persister) does not store ControlState in the session. In order to force it, you should add the following settings to your web config.

<system.web>
    <browserCaps>
      <case>
        RequiresControlStateInSession=true
      </case>
    </browserCaps>
</system.web>

Best wishes,

Hello there,

That one solved my problem! I guess that is worth mentioning in the documentation. I am not sure why I observed a relatively smaller viewstate before (it may be because of switching from RadWindow to RadDock).

Thanks!

Valery.

So with this setup you will still get something in the viewstate control? Is this the session variable id of the viewstate? or should the
viewstate value=""

this is what i get.

<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPZwUPOGNkNGEzYjc0MzE3MTkya87SkBtiHWiKhU9aaqPbGM3i/Jc=" />

Hi Mark,

Could you please try disabling an ASP.NET page ViewSate without using RadCompression at all and see if then you have the mentioned hidden field?

I tried that but it still shows up

I used <%@ Page Title="" EnableViewState="false"...... for a single page.

I also set the same for the master page that this page belonged to.

Hello Mark,

I think that this answers your questions. I assume you observed that with no RadControls on the page and in the application at all, when ViewState is disabled still a hidden field with name __VIEWSTATE is created/rendered. And that is why it persists when you use RadCompression as well.
