Operation Is Not Valid Due To The Current State Of The Object.

Hi:

I am writing a control that uses an edit page. On one machine the control works fine. But if I switch to another machine with a newer version of mojoPortal I receive the following error after hitting the "Update" mojo button:

Operation is not valid due to the current state of the object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Operation is not valid due to the current state of the object.

Source Error:

Re: Operation Is Not Valid Due To The Current State Of The Object.

It means one machine has the latest windows updates and the other one does not, and your page exceeds the new limit of 1000 form elements. The cause is a recent ASP.NET security update and a workaround is discussed on this thread.

Note that the hidden field sused for viewstate may be a significant factor in the number of form elements so setting EnableViewState="false" on any controls that don't need it may help.

Hope that helps,

Joe
