Unable to Validate Data

news · Dec 13, 2004

In .Net I get this error a lot but not always - "Unable to Validate Data"

It is a viewstate error.

Any ideas?

It's certainly a possiblity, although without more details about the
context of your message, it's hard to be sure. Check out
http://support.microsoft.com/default.aspx?scid=kb;en-us;831150#appliesto

And if that doesn't help, post more information about when in the
processing the error is taking place, along with the code that is being
executed when it happens.
