How to capture the rendered HTML for asp.net page?

[Paul W]

Hi - I want to be able to capture the html generated by one of my pages. Is
there any way to do this from within the application, or must I use some
form of 'screen-scraping'. If screen-scraping, can someone point me in the
right direction and indicate how I get past the login screen, etc.(uses
forms authentication)? Thanks,

Paul.

You can get the HTML for a control using this code:

Dim SB as New StringBuilder()
Dim SW as New StringWriter(SB)
Dim htmlTW as New HtmlTextWriter(SW)
MyControl.RenderControl(htmlTW)
Dim MyHTML as String = SB.ToString()

You can get the HTML for an external web page with the WebRequest method:

Override the page's Render Method as follows:

protected override void Render (HtmlTextWriter writer)
{
StringBuilder sb = new StringBuilder();
HtmlTextWriter tw = new HtmlTextWriter(new
System.IO.StringWriter(sb));
//Render the page to the new HtmlTextWriter which actually writes to
the stringbuilder
base.Render(tw);

//Get the rendered content
string sContent = sb.ToString();

//Now output it to the page, if you want
writer.Write(sContent);
}
