Hi Robert, adding nuanced label expressions can be accomplished by editing web maps creating in ArcGIS Online or ArcGIS Enterprise using the Map Viewer and working with Arcade expressions.   Arcade provides formatting functions as well as global variables that provide direct access to features in the map for labeling purposes.  Here is an example web map that illustrates the process involved. ...

Hi Brendan; It's a common question; in most cases it makes sense to combine fewer layers in a service for multiple reasons: performance, cartographic display, user experience, etc. arcgis server - Lots of layers in one or multiple services? (and why) - Geographic Information Systems Stack Exchange‌ While there isn't a magic number, there is usually a practical ceiling for managing layers within the same service. ... View more

HI Gauri, this sample illustrates how to get a map from the web map response: Web map using JSON | ArcGIS API for JavaScript‌ The key aspect of the sample is using the arcgisUtils class to create a deferred object, then obtain the map from the response. arcgisUtils.createMap(webmap,"map").then(function(response){       var map = response.map; //do something with the map here ...

I have been playing around with WMS layers in a WPF application but am having some difficulty getting any WMS layers to display when using a service not given in the WMS_WPF sample (for v1.2 of the API). Using either this sample solution or the Toolkit.Datasources assembly in v2.0 I get the same problem. What am I missing? I have the following piece of xaml nested in the Map.Layers section of the WMS_WPF sample solution <esriWMS:WMSMapServiceLayer ID="MyLayer" Layers="2909_17518_bg" Url="http://aes.gsfc.nasa.gov/cgi-bin/wms" Opacity="0.7"></esriWMS:WMSMapServiceLayer> equivalently, <esriToolkitDS:WmsLayer ID="MyLayer" Layers="2909_17518_bg" Url="http://aes.gsfc.nasa.gov/cgi-bin/wms" Opacity="0.7"></esriToolkitDS:WmsLayer> in v2.0 of the API.
