Issue with the Update Panel after deploying to the server.

Dear all,

I have an issue with update panel. I have a code a gridview. For refreshing issue, i had put the update panel outside the gridview. All these codes are inside tabcontainer.When i run the code on the local host then it works as expected wtihout refreshing.But when i deploy on the server the grid view on the click of calendar redirects to an error page.Here am not able to find the error also since its in server.Please let me know whether the update panel will work with tabcontainer or it has an issue.

Thanks
