如何从后面的代码中的当前aspx页面获取内部html

Question

How would I be able to get the innerHtml of the current aspx page in codebehind? I want to use the innerHTML and pass to a pdf converter function when the user clicks the pdf button, but i need the current page html as string.

Answer 1

我会回发并使用javascript提供当前的innerHTML

__doPostBack(**event target**, document.documentElement.innerHTML);

Answer 2

You can override Render method of the page.

protected override void Render(HtmlTextWriter writer)
{
     StringBuilder sb = new StringBuilder();
     HtmlTextWriter tw = new HtmlTextWriter(new StringWriter(sb));
     base.Render(tw);
     string innerHtml = sb.ToString();
}

innerHtml will contain whole rendered html code of page. A little simplified version.
