Sending KeyPress Events to browser using DotNetBrowser

Question

I am trying to fire OnChange event of an input element. Changing the value of the element does not fire onChange event. Is it possible to send a keypress to the browser in order to fire onchange event of the input element.

Yes, it is possible to send key down and key up events to the browser:

        browser.FinishLoadingFrameEvent += delegate(object sender, FinishLoadingEventArgs e)
        {
            if (e.IsMainFrame)
            {
                // The page is loaded completely. Press TAB key to set focus to text field.
                KeyParams paramers = new KeyParams(VirtualKeyCode.TAB, ' ');
                browser.KeyDown(paramers);
                browser.KeyUp(paramers);

                // Type 'Hello' text in the focused text field.
                paramers = new KeyParams(VirtualKeyCode.VK_H, 'H');
                browser.KeyDown(paramers);
                browser.KeyUp(paramers);

                paramers = new KeyParams(VirtualKeyCode.VK_E, 'e');
                browser.KeyDown(paramers);
                browser.KeyUp(paramers);

                paramers = new KeyParams(VirtualKeyCode.VK_L, 'l');
                browser.KeyDown(paramers);
                browser.KeyUp(paramers);

                paramers = new KeyParams(VirtualKeyCode.VK_L, 'l');
                browser.KeyDown(paramers);
                browser.KeyUp(paramers);

                paramers = new KeyParams(VirtualKeyCode.VK_O, 'o');
                browser.KeyDown(paramers);
                browser.KeyUp(paramers);
            }
        };
