What I want is that when I click on the button to get all the html source code rendered of the aspx page in a variable so I can send it in a mail. how can I get the rendered html source code from code behind function.

I actually just wrote a method for this not too long ago. It gets the view at a provided relative path, passes in a provided model, and renders the view as a string.

public static string RenderViewToString(string relativePathToControl, object viewData)
{
    ViewPage viewPage = new ViewPage() { ViewContext = new ViewContext() };

    viewPage.ViewData = new ViewDataDictionary(viewData);
    viewPage.Controls.Add(viewPage.LoadControl(relativePathToControl));

    StringBuilder sb = new StringBuilder();
    using (StringWriter sw = new StringWriter(sb))
    {
        using (HtmlTextWriter tw = new HtmlTextWriter(sw))
        {
            viewPage.RenderControl(tw);
        }
    }

    return sb.ToString();
}

You may need to add a few using statements.
