Displaying legend symbology in infowindow popup?

VincentChoffrut — Wed, 29 Apr 2015 14:22:28 GMT

hello everyone,

my map has a nice legend dijit and a click on some particuliar objects of the map pops up an infowindow dijit with the selected fields as a content, this is just FINE.

NOW I wonder whether it would be possible that the infowindow dijit displayed the same thing as the legend dijit, meaning the symbology of the particuliar object which is actually clicked?

I hope this question is clear...

I've tried several ways but I can't seem to find where the symbology of the objets is managed in arcgisServer (somewhere in LayerInfo?) and how to select it for diplaying in an infowindow.

I hope this is possible,

thanx in advance!

I have not done this but the REST API can return a layer's legend information as a JSON object. Within the framework of the Javascript API, you would use the esri/request object to obtain the legend info via the REST API call. Again, I haven't done this but it is covered in Rene Rubalcava's ArcGIS Web Development book on page 53.

One option might be to use the template picker to display the selected features symbol. Here's an example of how this works:
