how to know if gecko browser completed loading a webpage?

Question

As the title says, how can i know if the gecko browser completed loading a web page? I know there is document_completed event. But it will get triggered for every time a web page loads. Are there any other ways to check if the current webpage is completed loading.

My Solotion in vb.net and GeckoFX v45.0.34.0 you can use this tool convert to c# (http://converter.telerik.com/):

Private vWeb As GeckoWebBrowser = New GeckoWebBrowser
Private Property pageready As Boolean = False

Private Sub WaitForPageLoad()
    AddHandler vWeb.DocumentCompleted, New EventHandler(Of GeckoDocumentCompletedEventArgs)(AddressOf PageWaiter)

    While Not pageready
        Application.DoEvents()
    End While

    pageready = False
End Sub

Private Sub PageWaiter(ByVal sender As Object, ByVal e As GeckoDocumentCompletedEventArgs)
    If vWeb.IsBusy = False Then
        pageready = True
        RemoveHandler vWeb.DocumentCompleted, New EventHandler(Of GeckoDocumentCompletedEventArgs)(AddressOf PageWaiter)
    End If
End Sub

Using:

vWeb.Navigate("https://www.google.com")
WaitForPageLoad()
//Do your Work

Hope this solution to resolve.
