Welcome to SO. You can trigger the change event after entering the value in the eleInputboxA IJavaScriptExecutor js = (IJavaScriptExecutor)driver; js.ExecuteScript("arguments[0].dispatchEvent(new Event('change', {'bubbles': true,'cancelable': true}));",eleInputboxA); *Change the event name based on the associated event.
