@Paul – This article was written back in 2007, the MVC framework has changed quite a bit since then. Sorry you didn’t find what you needed.

This did not work for me. The field name (in the example it would be “hiddenBalance” could not be found.

No difference for me, really.

I resolved this by keeping the hidden field as before but adding a custom validator to compare the hidden field value.

and in javascript added the following func:

function comparefunc(sender, args)
{
var hid = document.getElementById(“”);
var text = document.getElementById(“”);

if (hid.value == text.value)
{
//values have not changed
args.IsValid = true;
return;
}

args.IsValid = false;
return;
}

Make sense??

I was able to bypass this error by changing my hidden items (I was using two asp:labels) and making them asp:textboxes instead. My problem was due to the fact that asp.net doesn’t know which field to validate when using a label, but a textbox is easy (it’s the text field).

Don’t know if that was the same issue you had, but thanks for the insite.
