Where is tileInfo property?

miguelde_la_roda

Hello!

If I declare a ArcGISTiledMapServiceLayer

var tiledMapServiceLayer  = new esri.layers.ArcGISTiledMapServiceLayer(routeMap); var num_levels = tiledMapServiceLayer.tileInfo.lods.length;

the new object tiledMapServiceLayer does not contain tileInfo property. Why? Do I need to configure ArcGIS Server?

Thank you!

You need to wait until the layer is loaded. If this is the basemap you are adding you can listen for the map's onLoad event and check the tileInfo then. Here's a snippet that shows how this works:

         basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer");                  dojo.connect(map,'onLoad',function(){            console.log(basemap.tileInfo.lods.length);         })         map.addLayer(basemap);

..and thank you from me. I have been playing with this code

To add watermarks - I was putting it all in the init function, rather than the onload - saw this post, moved it, and it all works. Now of course Esri will probably add a watermark feature in the next release or something, but who cares 😄
