    HTM page manipulation

    I want generally to get information about a web page. I manage to get the htm code and save it, in order to parse it. But the page (.aspx) has multiple pages that you can select by pressing selecting the page.

    I know that if I select the page it will do
    Code:
    javascript:_doPostBack(something)
    Can I do this programmatically? Like force it to execute the javascript function with the specific parameter I choose? Is there another way to make it load a page that you don't know the specific link?

    Here is the javascript function
    Code:
    function __doPostBack(eventTarget, eventArgument) {
        if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
            theForm.__EVENTTARGET.value = eventTarget;
            theForm.__EVENTARGUMENT.value = eventArgument;
            theForm.submit();
        }
    }
    There are two hidden fields __EVENTTARGET and __EVENTARGUMENT in the form.
    I would want
    1) to get those fields
    2) change them accordingly
    3) force the page to postBack

    Can I do this with GET/POST methods from the HttpWebRequest? This is a whole new field from me

    (why am I filling alone? :P)

    Well, googling around didn't give me any answer. But I found an intersting class called
    WebBrowser. It just lets you do whatever you want, simple as that.
