Answer 1

for the client side

In Internet Explorer

Right click on browser -> View Source

In firefox

Right click on browser → View Source page

for the server side

You can override the way your page renders to capture the server side HTML source.

protected override void Render(HtmlTextWriter writer) { // setup a TextWriter to capture the markup TextWriter tw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(tw); // render the markup into our surrogate TextWriter base.Render(htw); // get the captured markup as a string string pageSource = tw.ToString(); // render the markup into the output stream verbatim writer.Write(pageSource); // remove the viewstate field from the captured markup string viewStateRemoved = Regex.Replace(pageSource, "<input type=\"hidden\" name=\"__VIEWSTATE\" id=\"__VIEWSTATE\" value=\".*?\" />", "", RegexOptions.IgnoreCase); // the page source, without the viewstate field, is in viewStateRemoved // do what you like with it } 

Answer 2

Override the Render method and call base.Render with your own HtmlWriter.

Answer 3

Are you sure you want to parse HTML? This is a difficult business. If you don’t have to do this, I would avoid it using DOM methods on the client side (if the client-side solution is acceptable). If you do this a lot, you can consider jQuery , Prototype, or some other tool that will help.
