How to click buttons/links which are in iframe? (GeckoFx)

Question

This code access iframe and gets me source code.

string content = null;
var iframe = browser.Document.GetElementsByTagName("iframe").FirstOrDefault() as Gecko.DOM.GeckoIFrameElement;
if (iframe != null)
{
    var html = iframe.ContentDocument.DocumentElement as GeckoHtmlElement;
    if (html != null)
        content = html.OuterHtml;

    textBox1.Text = content;
}

I tried puting some code

string content = null;
var iframe = browser.Document.GetElementsByTagName("iframe").FirstOrDefault() as Gecko.DOM.GeckoIFrameElement;
if (iframe != null)
{
    var html = iframe.ContentDocument.DocumentElement as GeckoHtmlElement;
    if (html != null)
        content = html.OuterHtml;

    textBox1.Text = content;

    GeckoElementCollection elements = browser.Document.GetElementsByName("username");
    foreach (var element in elements)
    {
        GeckoInputElement input = (GeckoInputElement)element;
        input.Value = "Auto filled!";
    }
}

But it wont work as code dont find elements. Any ideas?

Tried searching google for any iframe examples but seems that there isnt any good documentation for it.

I know selenium webdriver and I tried but I need to work with firefox browser (geckoFx) — Aasas

Why are you looking for in the main document? You should look for in a frame.

string content = null;
var iframe = browser.Document.GetElementsByTagName("iframe").FirstOrDefault() as Gecko.DOM.GeckoIFrameElement;
if (iframe != null)
{
    var html = iframe.ContentDocument.DocumentElement as GeckoHtmlElement;
    if (html != null)
        content = html.OuterHtml;

    textBox1.Text = content;

    GeckoElementCollection elements = iframe.ContentDocument.GetElementsByName("username");
    foreach (var element in elements)
    {
        GeckoInputElement input = (GeckoInputElement)element;
        input.Value = "Auto filled!";
    }
}

Oh, "browser.Document" is main document. "iframe.ContentDocument" iframe doc. Thanks for help!
