AjaxControlToolkit ValidatorCalloutExtender does not work with UnobtrusiveValidation

description

Hi,

I have a WebForms application. If I target the application to use .NET 4.6 framework, the ValidatorCalloutExtender does not work. If I switch off the UnobtrusiveValidation, the validation works fine. We don't want to turn off the UnobtrusiveValidation setting. Is there any other solution?

Thank you.

Hello,
 
ValidatorCalloutExtender relies on the old way of validation, which is not compatible with unobtrusive validation. We are aware of this issue and are looking for ways to resolve it.
However, unobtrusive validation depends on jQuery, but AJAX Control Toolkit does not use it, so there is no guarantee that this extender will be forward-compatible with .NET Framework 4.5+

Hi Mikhail,

Thank you very much for the response. Going forward, are there plans to use jQuery with Ajax Control Toolkit or if otherwise, deprecate this control? Are there any other known issues to look out for with Ajax Control Toolkit vis-a-vis .NET 4.6?

Currently, we do not plan to implement jQuery support in Ajax Control Toolkit. However, we won't deprecate this control in the near future either. In any case, there is no need to be concerned. If we decide to deprecate a control, we always provide an alternative with a similar functionality.
As regards .Net 4.6, the AJAX Control Toolkit will operate correctly in it while the framework supports backward compatibility.

Thank you for the clarification Mikhail.

I stumbled upon this link about Ajax Control Toolkit and jQuery http://stephenwalther.com/archive/2013/09/30/ajax-control-toolkit-now-supports-jquery

Just curious.. has this effort been abandoned?

Yes, these changes were rolled back. We wrote about it in What’s New in v15.1 when released AJAX Control Toolkit v15.1.
