Calling javascript function from HtmlAgilityPack

I want to use HtmlAgilityPack in a form application to read some pages content but on the page search subpage I need to invoke the javascript and the link looks like this:

<a href="javascript:__doPostBack('lnkbtnNext','')" id="lnkbtnNext">Następny >></a>

How ca开发者_JAVA百科n I Call this function from my C# desktop application?

If you trust the source, it looks to me like you'd be better off invoking the WebBrowser control. HtmlAgilityPack does not provide a scripting engine.
