I found the solution. It looks like with Infragistics 2012, the control has ":v:" after it. So I just updated Client\MicrosoftAjax.Extended\ValidatorCallout\ValidatorCalloutBehavior.pre.js with the following change:

var elementToValidate = this._elementToValidate = $get(elt.controltovalidate.replace(":v:", ""));

Now the ValidatorCalloutExtender appears in the proper position.

Hi Trent,

You probably refer to difference between old WebMaskEdit and new WebMaskEditor controls. Those are completely different controls, though, they use similar functionality.

I guess in your codes you should remove prefix "igtxt" and use something like

elem = $get(elt.controltovalidate);

Hi,

It looks like in Infragistics 2012, the hidden fields does not begin with "igtx" anymore. So now the message appears in the upper left corner again.
