JQuery tabs + ViewState corrupt error after first postback

JQuery tabs + ViewState corrupt error after first postback

Hello,
         I am using JQuery Tabs in a Profile page. In Profile I have Five tabs. In a First tab I have displayed some basic information related to Profile like First Name, Last Name, Email, Website etc....but its long page. First tab is inside the Profile Page itself. In second tab I have displayed Contact Information of the Profile. In contact Information Profile I will have multiple contacts and each Contact will have multiple Phone numbers and email address. For the second tab I am using different page. In Third tab I have displayed Address information of the Profile. Same like Contact Profile will have multiple Address. I have done such code that will display the City and State of entered Zipcode of India. This functionality works like When user enters the Zipcode in textbox then autopostback will be done the and by the zipcode it will fetch the state and city names. This functionality works very fine in other page, but when I put this page is Tab panel I just stop working. It works only first time. Then it stops the postbacking the data. I tried to find the root of the problem and found that when I do the postback second time I am getting such an error '70|error|500|The state information is invalid for this page and might be corrupted.|' . This happens in all the three major browses. I don't get solution yet. 
How can I stop the ViewState being corrupt or any other solution that start the postbacking the data?

Please help me to find the solution.
