java script error is coming when we are using Telerik Calendar control in a page, and if we use SetFocusOnError="true"

Property.
Moreover we have used the ajax validator extender.
Please refer attachment.
can anyone have idea about any possible solutions?

Hello Rikin,

This error can occur if you are using an older version of our controls in .Net 4.0. Please ensure you have updated to our latest release and let us know if you find any problems. You can read the following article for more details on how to upgrade:

Hi Rikin,

You can add the following script to the body tag of the affected page:

<script type="text/javascript">
        if (typeof (ValidatedControlOnBlur) == "function") {
            ValidatedControlOnBlur = function (event) {
                event = event || window.event;
                var control;
                if ((typeof (event.srcElement) != "undefined") && (event.srcElement != null)) {
                    control = event.srcElement;
                }
                else {
                    control = event.target;
                }

                var isRadInputControl = false;
                if ((control.style)
            && (typeof (control.style.visibility) != "undefined")
            && (control.style.visibility == "hidden")
            && (typeof (control.style.width) != "undefined")
            && (document.getElementById(control.id + "_text") || document.getElementById(control.id + "_dateInput_text"))
            && (control.tagName.toLowerCase() == "input" || control.tagName.toLowerCase() == "textarea")) {
                    isRadInputControl = true;
                }

                if ((typeof (control) != "undefined") &&
            (control != null) &&
            (Page_InvalidControlToBeFocused == control)
        ) {
                    if (isRadInputControl && document.getElementById(control.id + "_text")) {
                        document.getElementById(control.id + "_text").focus();
                    }
                    else if (isRadInputControl && document.getElementById(control.id + "_dateInput_text")) {
                        document.getElementById(control.id + "_dateInput_text").focus();
                    }
                    else {
                        control.focus();
                    }

                    Page_InvalidControlToBeFocused = null;
                }
            }
        }

    </script>

Hope this helps.
