type and position of the controls added during the initial request. ---> System.Web.HttpException: Failed to load viewstate.

Try clearing your browser's cache and try again.

Thanks for ur reply.Yes i have tried this solution.Should i refresh the browser every time to make a change. Is there way that i can proceed without browser refresh.

Thanks,

you should not need to make a browser refresh every time, only if you receive a viewstate error, which you should only come across very occasionally. If you receive these often, then you need to make a note of exactly what you are doing before the error occurs.

Thanks,
