How to raise a System KeyDown event  manually in .Net Compact framework 3.5
===

I have developed a custom keypad using resco controls in my application I have currently handled the backspace button click event with the following code


private void customKeyboard1_KeyboardKeyUp(object sender, Resco.Controls.Keyboard.KeyPressedEventArgs e)
        {
            if (e.Key.Text == "Backspace")
            {
                Resco.Controls.Keyboard.CustomKeyboard.SendBackspace();
                e.Handled = true;
            }
        }


This works fine with the edit boxes in the application but not working in edit boxes in the web pages (for eg. on gmail username text box).

so is there any way to raise the KeyDown event manually
