Event : after loading map serive layer

Hi All,

I have added online map service(Eg. World Street Map) into ArcMap using ArcObject API.
I am trying to implement zoom to location programmatically on the layer.Some time layer will take more time to load tiles and zooming is not working properly.

Is there any event available which will fire after loading all tiles? or i will get notification once layer loaded completely.

Thanks in advance,
Prashant
