The state information is invalid for this

[john]

Hello,

I am using the radgrid (with embeded user control for insert/updates) and am getting the below error.  I looked at prior threads on this and didn't get much info.  I am using iis for dev.  The viewstate is rather long -- just like the other person who had this issue.  Does your product have a solution for this?

Thanks,
John
