RadAjaxLoadingPanel disables ASP Validators

[Bruce Dimon]

I have a web form with text boxes and ASP Validators. I wanted to add a RadAjaxLoadingPanel to give some feedback when the code was updating. The AjaxUpdatedControl disables all of the ASP Validators. The Javascript for the ASP Validators is not in the page source. The XmlHttpPanel_ServiceRequest is empty in the code-behind. If I comment out the AjaxUpdatedControls, the validators work!

Hi Bruce,

When ajaxifying controls using the RadAjaxManager, you are actually specifying which controls will be updated, and which controls will trigger the ajax requests. In your case only the XmlHttpPanel will be updated, when any of the buttons are clicked. Any validators (or in fact any other controls) that are affected by the buttons' click events will not be updated. This on the other hand will not cause the client validation to not work, since it does not depend on whether a control is ajaxified or not.
I tested your code locally, with some modifications, and the client validation works correctly. Please find it attached to the thread. Please note, that the RadXmlHttpPanel does not support ASP.NET validation, and you need to implement your own way to make sure the data entered is correct.


Kind regards,
