Web Method can be used for Two purpose

You won't get the updated value of Hidden field in web method because web method run in the server and server doesn't aware about value changes done in client side before Postback.

if your purpose of web method is AJAx Call ,
you can send the updated value of hiddenfiled as a parameter value in ajax call.

yes shazid .. i am agree with you but if i send as a parameter during the ajax call the updated hiddenfield value i wont get it for next scope ..

you can try to update the HIddenfieldValue in the web Method like :
[webMethod()]
public static string test (string hfValue)
{
hiddenField.Value = hfValue;

....other ...business ..owrk
}

This way you can update server state of that HidenField

it wont allow me to access hideenfield inside webmethod .. no server control can be accessable inside webmethod ... and thats what the problem is

Then you have to send the updated value Every time you call
