this is a strange case i have.

i have a textbox an ajaxpanel with the textchanged event fired when the textbox is filled through code.

the strange thing is that it works fine, but if i use validation, and the validator fails, then the next textchange will not fire the ajaxpanel!!! i even tried calling the ajaxRequest explicitly, and still it didnt fire nor called the ClientEvents-OnRequestStart event, if however i re-change the textbox again to another value without validating again, it fires normally !!!!

i tried to trace this for to no avail.

unfortunatly, i cannot post code here, but i can provide you with a link (PRIVATLY) so that you can see what i mean.

Hello Basel,

Please try setting the EnableClientScripts property of the validators to false and check if this helps.

Hello Basel,

The only limitation is that they would work only in Full Level trust environments (i.e would not work on shared hostings). For shared hostings, please use server validation by setting the EnableClientScripts property of the validators to false.

Kind regards,

I am having the same problem. When I have done something on the page to trigger client validation and the validation fails I am no longer able to call the "ajaxRequest()" method off of a RadAjaxManager instance in client script. If client validation has not been invoked everything works as expected. To reproduce:

  1. Create a standard page with a couple of textboxes and required field validators.
  2. Add two buttons - one triggers standard validation and one calls a client-script method that initiates an ajax request to do something insignificant (perhaps update a label on the page or something).
  3. Start filling in the form, intentionally leaving a required field blank.
  4. Hit the button that causes client-side validation to fire and shows the error about a required field missing.
  5. Now hit the other button that triggers the ajaxRequest() method. You'll notice this method does not fire nor does your method get invoked on the server-side.
What is the best way to resolve this? The way I am utilizing the ajaxRequest method is to update the records in a grid and it needs to fire regardless of whether client-side validation has been invoked (and failed).

Any resolution to this? We are having the same issue as Scott on Q2 2012 SP2.

EDIT: Seems our issue was not caused directly by client side validation, but rather a call to Page_ClientValidate() without Page_BlockSubmit = false;. Resolution was discussed here: http://www.telerik.com/community/forums/aspnet-ajax/ajax/radajaxmanager-calling-page-clientvalidate-seems-to-break-ajaxmanager.aspx
