How to get SimpleRenderer.ToJson to include Symbol?

Anonymous User — Sat, 11 Dec 2021 13:43:56 GMT

With a featurelayer created from this:

https://services2.arcgis.com/ZQgQTuoyBrtmoGdP/arcgis/rest/services/Redlands_Restaurants/FeatureServer/0

featureLayer.Renderer.ToJson() returns json that lacks the symbol:

{
 "symbol": {},
 "type": "simple"
}‍‍‍‍‍‍‍‍

But ((SimpleRenderer)featureLayer.Renderer).Symbol.ToJson() returns this:

{
  "symbol": {
    "angleAlignment": "Display",
    "symbolLayers": [
      {
        "anchorPoint": {

Are you on an older version of runtime? I believe those symbol types weren't fully supported until more recent versions.

This is with 100.7 WPF on .NET framework 4.8.

If feature table has advanced symbology , it is as designed that Renderer.ToJson will return empty symbol info and ((SimpleRenderer)Renderer).Symbol.toJson() will return the json of CIM Symbol.

Since the service you had has AdvancedSymbology enabled, what you are getting is as expected.

If you to access the simple symbol as advertised in layer's metadata you can turn FeatureTable.UseAdvanceSymbology=false before loading the table.

Uri serviceUri = new Uri("https://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer/0");
var table = new ServiceFeatureTable(serviceUri);
table.UseAdvancedSymbology = false;
await table.LoadAsync();
// Create new FeatureLayer from service uri and
FeatureLayer fLayer = new FeatureLayer(table);
var str = fLayer.Renderer.ToJson();

NOW YOU WILL GET FOLLOWING FROM RENDERER.TOJSON()
{"symbol":{"angle":0,"color":[255,255,115,255],"outline":{"color":[0,0,0,255],"style":"esriSLSSolid","type":"esriSLS","width":1},"size":4,"style":"esriSMSCircle","type":"esriSMS","xoffset":0,"yoffset":0},"type":"simple"}‍‍‍‍‍‍‍‍‍‍
