Hello,

Yes, you can change this error message into others message. To do that, you could use OnUnhandledError client side event.

“Unable to communicate with server.” error will returns empty string in OnUnhandledError client side event. I suggest you to use following conditional statement in order to handle the error.

<script type="text/javascript">
    <!--
    function WebGrid1_OnUnhandledError(controlId, action, lastRequestObject, errorString) {
        var WebGrid1 = ISGetObject(controlId);
        if (errorString == "") {
            // Put your error handling script in here.
        }
        return true;
    }
    -->
</script>

You could find more information about this event in WebGrid’s documentation.

Hope this helps. Thank you.

// Put your error handling script in here

Hello,

Let me show the example format code in OnUnhandledError() function.
Here’s the script below:

        function WebGrid1_OnUnhandledError(controlId, tblName, lastRequestObject, errorString) {            var WebGrid1 = ISGetObject(controlId);
            //delay function before call errorBox() function
            window.setTimeout(function () { errorBox(); }, 50);
            return true;
        }
        
        function errorBox() {
            // Get the object of ErrorMessage's Window
            var errorMessage = document.getElementById("wg_ErrorMsg");
            var box = errorMessage.parentNode.parentNode.parentNode.parentNode.parentNode.style;
            // Set the size of ErrorMessage's Window
            box.width = "500px";
            box.height = "500px";
            // Set your own ErrorMessage's text
            errorMessage.innerText = "Your Own Error Message";
            document.getElementById("tdStatIcon_WebGrid1").style.display = "none";
            document.getElementById("tdStat_WebGrid1").childNodes[0].childNodes[0].nodeValue = " ";
        }

Hope this helps. Thank you.
Regards,
Hans.
