:) sorry, its been a busy week. Does Ryan's fork linked above work for you? I haven't tried it yet.

Let me go try that out. Thanks a lot for writing it and putting it out for us to use in the first place! :D

You can see it working at http://opengis.azexperience.org/vae/azcentennial/

Yes, Ryan's changes worked. Thanks! :D

It'll also be nice if you could explicitly state what license this code is under...

Great point. I've updated this Gist with Ryan's changes (untested) and appropriate license and copyright details.

Cheers

There are still problems, I think, if you want to have more than one Bing layer in your app.

Issue with multiple Bing Layers and attributions being added multiple times:

Replace

`````` this._map.attributionControl.removeAttribution(this.attribution);```

with

    this._map.attributionControl._attributions = {};
    this._map.attributionControl._update();```

Forked here:

updated gist with ccgdesigns contribution.

When I try to overlay a custom tilelayer over the bing layer, the bing one always supersedes. As in, I want the custom layer to be on top. The custom layer falls under the aerial imagery, so i don't see it at all!

This code has been incorporated into https://github.com/shramov/leaflet-plugins, I suggest following up there.

Hi,
We are using leaflet with bing map
I am wondering if it is possible to retrieve session id to decrease billable calls to bingmap
If we use session id instead of key after first call they are nonbillable.
For bingmap ajax there is getcredentials function but I could not find anything similar with leaflet.
callback function only includes traceid.
Thanks

Hi everybody, I'm trying to add tile bing to my map, espacially 'AerialWithLabels' type. So do you have any idea how to use that? I'm using leaflet with angularJS. Honestly, I'm beginner in leaflet.

Any help is appreciated. Thankx for advance
