Xamarin Mac application doesn't react when I try to allow it in Dropbox

Question

I am developing a Xamarin Mac application and I need to do some data syncing with Dropbox.

I have created a WebView which navigates to a URL where the user is prompted to enter its username and password. After hitting OK and successfully signing in I am presented with a new screen where I can grant or deny the app access to it's folder in Apps > AppName inside Dropbox.

Regardless of hitting Cancel or Allow nothing happens. If I however click on the Dropbox icon on the top left I am navigated normally to my dashboard.

I thought that this might be a Javascript problem or something similar but I have changed all the properties I can think of and I am still stuck on the same page.

What I need to set to be able to move on?

I have found the solution for my problem which is quite a strange one (IMO) but maybe it's the default way on OSX.

I subscribed to all event's the webView control has to offer and I found this "nugget".

Once the user clicked on "Allow" the CancelClientRedirect event was raised and by chance I found out that if you check out the

YourWebViewControl.MainFrameUrl

you could see which callback URL should have been called.

It would either be http://yoururl.com/oauth=someRandomString or http://yoururl.com/not_approved=true.

Based on this URL you can then know what happened (i.e. app (not) authorized) and then do whatever you want in response to that.

Hope this might help someone out!
