I think you are missing the "SetDefinition" call on the layerdef. There is a snippet that shows what you want to do here: Change the layer selection color EDIT: sorry - looks like that snippet hasn't posted yet. This is it: var featureLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault(); ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() => {    // get the CIM definition of the layer    var layerDef = featureLayer.GetDefinition() as ArcGIS.Core.CIM.CIMBasicFeatureLayer;    // disable the default symbol   layerDef.UseSelectionSymbol = false;    // assign a new color   layerDef.SelectionColor = ColorFactory.RedRGB;    // apply the definition to the layer   featureLayer.SetDefinition(layerDef);    if (!featureLayer.IsVisible) featureLayer.SetVisibility(true);    //Do a selection   MapView.Active.SelectFeatures(MapView.Active.Extent); }); ...

Hi Luke, We have to edit the unique value renderer itself, once it has been made. I have provided some code below. Note: I encourage you to look at the samples for the CIM at https://github.com/esri/arcgis-pro-sdk-community-samples/tree/master/Map-Authoring/CIMExamples. I based the code snippet below on the source code in 'CreateCIMRendererFromScratch.cs'. It uses the U.S. States dataset available with the samples. internal class SetLabelsOnUniqueValueRenderer : Button {         protected async override void OnClick() {             var usStatesLayer =                 MapView.Active.Map.GetLayersAsFlattenedList().FirstOrDefault((fl) => fl.Name == "States") as                     FeatureLayer;             if (usStatesLayer == null) {                 MessageBox.Show("Please add the 'States' layer to the TOC - with a 'STATE_NAME' field containing state names.", "Cannot find US States");                 return;             }             //make a unique value renderer             await CreateUniqueValueRendererOnStatesAsync(usStatesLayer);             SetLabelsOnStatesRendererAsync(usStatesLayer);         }         private Task CreateUniqueValueRendererOnStatesAsync(FeatureLayer fl) {             return QueuedTask.Run(() => {                 var uvrDef = new UniqueValueRendererDefinition() {                     ValueFields = new string[] {"STATE_ABBR"},                     SymbolTemplate = SymbolFactory.DefaultPolygonSymbol.MakeSymbolReference(),                     //Simple ramp                     ColorRamp = new CIMLinearContinuousColorRamp() {                         FromColor = CIMColor.CreateRGBColor(0, 255, 0, 60),//Green, partially transparent                         ToColor = CIMColor.CreateRGBColor(255, 0, 0, 60),//Red,  partially transparent                         ColorSpace = new CIMICCColorSpace() {                             URL = "Default RGB"                         }                     }                 };                 fl.SetRenderer(fl.CreateRenderer(uvrDef));             });         }         private Task SetLabelsOnStatesRendererAsync(FeatureLayer fl) {             return QueuedTask.Run(() => {                 var renderer = fl.GetRenderer() as CIMUniqueValueRenderer;                 //A UniqueValue renderer has one or more CIMUniqueValueGroups. In this example                 //there is only one CIMUniqueValueGroup (otherwise use a 'foreach(var group in ....)'                 var group = renderer.Groups[0];                 //Each group has one or more CIMUniqueValueClasses - in this case we have one class per                 //STATE_ABBR value. Note: The default value and label are on the renderer itself                 //(renderer.DefaultLabel, renderer.DefaultSymbol) and are NOT in a class.                 foreach (var valClass in group.Classes) {                     //Each CIMUniqueValueClass has a Label (what you are after 😉 and an array of CIMUniqueValues                     //As our values are unique, we have one CIMUniqueValue per class.                     //Get its field value (read from STATE_ABBR) and change the label to be the state name                     if (valClass.Values[0].FieldValues[0] == "AK")                         valClass.Label = "Alaska";                     else if (valClass.Values[0].FieldValues[0] == "AL")                         valClass.Label = "Alabama";                     else if (valClass.Values[0].FieldValues[0] == "AR")                         valClass.Label = "Arkansas";                     else if (valClass.Values[0].FieldValues[0] == "AZ")                         valClass.Label = "Arizona";                     //etc,etc                 }                 fl.SetRenderer(renderer);             });         }     } ...

The easiest way would be to create the layer using LayerFactory and then apply the symbology to the layer (you just created) using Geoprocessing.ExecuteToolAsync() and the layer file. Something like: var gpresult = await Geoprocessing.ExecuteToolAsync("ApplySymbologyFromLayer_management", new string[]                       {theNewLayerName,@"C:\Location\my_layer_file.lyr"}); Here are some links that might help: Apply Symbology From Layer Performing Geoprocessing Create and Add a Layer to the Active Map ...

Hi Ted, Good question. Comes down to priorities basically - we templatized the most commonly used controls (20 templates at 1.2) and the controls that are more obscure we did not. If lots of people want to use checkboxes or spinners on custom tabs we can look at adding templates for them. Otherwise, as you noted, just add them by hand. On the core tabs they are rarely used. ... View more
