Is there any way through which I can get HTML of my current page. By current page I mean let's say I am working on Default.aspx and want to get HTML by providing a button on it.

How to get it.

EDITED in response to clarification of the requirements

You can override the page's render method to capture the HTML source on the server-side.

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
}
