    Hi Jay,

     This error is not directly related to RadToolTipManager but could be reproduced with a standard update panel as well and usually occurs when something is wrong with the server code. You can find more information on the net, e.g below:


    This being said, I recommend to debug the server code.

    If the problem persists, you can cancel the error alert in the OnClientResponseError event as shown below:

    Copy Code
    <script type="text/javascript">
    function OnClientResponseError(sender, args) {

    i hope that my reply and suggestion are helpful, let me know how it goes.

    Kind regards,
