Click an HTML link inside a WebBrowser Control

Question

C# Visual Studio 2010

I am loading a complex html page into a webbrowser control. But, I don\'t have the ability to modify the webpage. I want to click a link on

Answer 1

Perhaps you will have to isolate the link ID value using more of the surrounding HTML context as a "target" and then extract the new random ID.

In the past I have used the "HtmlAgilityPack" to easily parse "screen-scraped" HTML to isolate areas of interest within a page - this library seems to be easy to use and reliable.

Answer 2

Something like this should work:

HtmlElement link = webBrowser.Document.GetElementByID("u_lp_id_58547")
link.InvokeMember("Click")

EDIT:

Since the IDs are generated randomly, another option may be to identify the links by their InnerText; along these lines.

HtmlElementCollection links = webBrowser.Document.GetElementsByTagName("A");

foreach (HtmlElement link in links)
{
    if (link.InnerText.Equals("My Assigned"))
        link.InvokeMember("Click");
}

UPDATE:

You can get the links within an IFrame using:

webBrowser.Document.Window.Frames["MyIFrame"].Document.GetElementsByTagName("A");
