Seems that the number of web controls instantiated on postback does not
match the number of controls saved in the viewstate.
It go to other problem say what cannot find the reference when run
cmd.ExcuteScalar().ToString()
Could you please specify the exact error message? I would assume you haven't
referenced System.Data.dll from your project but if you say you get the
error on runtime, I have no ideas except the CLR cannot locate this assembly
for some reason.
