I have a hidden value field on a page. On submit I post to a different page. On the page I've posted to I do a Request.Form but I do not get the value just a null value. This is the initial page

I'm having a time finding out I could not do something simple as :
On the onchange event getting the new selected checkbox, this with jquery.
The checkboxes are located in the following div :

I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
I have been searching the net and found no clean cut answer to my problem. I have an animated spinning gif, that is displayed within an 'UpdateProgress'. This gif is to be displayed when the page is posting back to the server and processing.
The animation will start to spin but basically stright away it stops. I have noticed that the file menu within IE is also frozen at this point, up untill the page fully refreshes. I have tested in firefox and safari and am recieving the same problems.

From the master page of my ASP.NET site I need to set the value of a hidden field in every get and post request and then subsequently read it in the next request.The problem is that in the post request the code works fine but when the client sends a get request I am unable to read the value of the hidden field from teh Master Page.
