Hi,
I'm getting the following error when requesting asp.net page.


Invalid postback or callback argument. Event validation is enabled using
<pages enableEventValidation="true"/> in configuration or <%@ Page
EnableEventValidation="true" %> in a page. For security purposes, this
feature verifies that arguments to postback or callback events originate from
the server control that originally rendered them. If the data is valid and
expected, use the ClientScriptManager.RegisterForEventValidation method in
order to register the postback or callback data for validation.

Any thoughts are welcome.

Thanks

the message is pretty clear. the browser is posting back a value for a
unknown control, or a value out of range. this usually happens when client
code changes the values of a dropdown. if so following the instruction in
the message.
