}

Answer 1

Here is the answer:

protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e)
{
  Browser.InvokeScript("functionName");
}

And parameter can also be passed from here like this:

protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e)
    {
      Browser.InvokeScript("functionName","param1");
    }
