C# - GeckoFX vs InnerHTML

If I would use default Visualstudio webBrowser control (IE) i would just write something like this:

textBox3.Text = webBrowser1.Document.GetElementById("mydivid").InnerHtml;

But I'm stubborn to use GeckoFX (Mozilla) and ofcourse it doesn't work. What I found is information that I need to adress "HTMLDocument" not "Document" to pull my desired value. But no example that fit my needs. How to get this innerHTML of this particular element?

--- Response to @Timothy Groote ---

I've read the other topic - there's no example of code with GetElementById, it's like wide definition, but I need specific one - I cannot read this codeand get clear information what method or property shoueld I use in my app.

I can add that my element is and will be always HTML element, so i don't need to verify that every time with "if".

When I use "the other code" in my app result (instead of innerHTML) was only:

<head></head><body></body>

In "the other code" has also a mistake:

var geckoDomElement = WebBrowser1.Document.DocumentElement;

There's no webBrowser1 control! Only geckoWebBrowser1, neither works!

--- Edit2 ---

I was also thinking about something like that:

textBox3.text = (GeckoHtmlElement)geckoWebBrowser1.Document.GetElementById("mydivid")....

but there's also no "innerHtml"

in

(GeckoHtmlElement)geckoWebBrowser1.Document.DocumentElement

there's no "getElementById".

Solution

  • ANSWER Of course defining variable:

    GeckoHtmlElement machcode;

    Finding element:

    machcode = geckoWebBrowser1.Document.GetHtmlElementById("machinecode");

    And finally reading the content:

    textBox3.Text = machcode.InnerHtml;

    And one important thing was to place code in DocumentComplete event!

    Every solutions provided in web were wrong - some point into nonexisting webBrowser1 control, some forget about definition, some throw null exception, some use wrong GetElement instead of GetHtmlElement.
