                if (element != null)
                {

        using (document)
        {
            dynamic elem = document.getElementById("txt1");

            if (elem == null)
                return "";

            using (elem)
                elem.value = "test";

I would use jQuery's attr() and jQuery's trigger():

webctrl.ExecuteJavascript("$(#txtFileNo).attr('value', '12345');");
webctrl.ExecuteJavascript("$(#BTN).trigger('click');");

Since you are targeting a single browser, you could use plain old Javascript for this against the Chromium DOM. But, I find jQuery's trigger() to be much easier to use than the alternative.
