C＃GeckoFX-从导航的页面调用JS函数

Question

I am trying to call my function "initialize" in the navigated page using GeckFX(version 33), I have tried the following actions:

_wb.Navigate("javascript:void(initialize());");

and

using (Gecko.AutoJSContext context = new AutoJSContext(_wb.Window.JSContext))
{
    var result = context.EvaluateScript("initialize();", _wb.Window.DomWindow);
}

both didn't work. the first one didn't even return an error, the second one returned the following error message:

Error HRESULT E_FAIL has been returned from a call to a COM component.

I am performing those actions in the "DocumentCompleted" event handler. Is there something I am missing?

my guess is that it didn't finish loading the page as when I stop in debug mode I don't see the web page from within this even handler(only when i continue it appears)

any ideas how to make it work? thanks.

I have found the issue, I should have used:

Application.DoEvents();

and then call

_wb.Navigate("javascript:void(initialize());");
