Having some issues using CIMRasterClassBreak that are really frustrating and I can't seem to solve it. For background, I'm trying to migrate an add-in functionality from Arcmap where a user selects a raster from those loaded into the TOC, and based on a starting elevation, number of classes, and interval between the classes, it reclasses the raster for display. This is helpful for lidar where you're trying to see subtle variations in topography.   Anyways, the ChangeColorizerForRasterLayer community sample largely pointed me in the right direction in terms of what part of the SDK I needed to focus on and I'm pretty much there, except for the actual task of modifying the class breaks. Here is the core code of my process: public static async Task SetToClassifyColorizer(BasicRasterLayer basicRasterLayer, Int32 numClasses, Double startElev, Double theIntervalSize) { // Defines values for parameters in colorizer definition. string fieldName = "Value"; ClassificationMethod classificationMethod = ClassificationMethod.DefinedInterval; int numberofClasses = numClasses; string colorRampStyle = "ArcGIS Colors"; string colorRampName = "Temperature"; await QueuedTask.Run(async () => { // Gets a color ramp from a style. IList<ColorRampStyleItem> rampList = GetColorRampsFromStyleAsync(Project.Current, colorRampStyle, colorRampName); CIMColorRamp colorRamp = rampList[0].ColorRamp; // Creates a new Classify Colorizer Definition using defined parameters. ClassifyColorizerDefinition classifyColorizerDef = new ClassifyColorizerDefinition(fieldName, numberofClasses, classificationMethod, colorRamp); classifyColorizerDef.IntervalSize = theIntervalSize; // Creates a new Classify colorizer using the colorizer definition created above. CIMRasterClassifyColorizer newColorizer = await basicRasterLayer.CreateColorizerAsync(classifyColorizerDef) as CIMRasterClassifyColorizer; var templateClassBreak = newColorizer.ClassBreaks[0]; var theClassBreaks = new ArcGIS.Core.CIM.CIMRasterClassBreak[numberofClasses]; var curValue = startElev; //Manually create a replacement set of class breaks. These needs a color symbol but that will be done in a separate step so just //asign it null for the time being for (int i = 0; i < numberofClasses; i++) { var curClassBreak = newColorizer.ClassBreaks[0]; if (i == 0) { curClassBreak.Label = "<= " + curValue.ToString(); } else if (i == (numberofClasses -1)) { curClassBreak.Label = ">= " + curValue.ToString(); } else { var preVal = curValue - theIntervalSize; curClassBreak.Label = preVal.ToString() + " - " + curValue.ToString(); } curClassBreak.UpperBound = curValue; curClassBreak.Color = null; theClassBreaks[i] = curClassBreak; curValue = curValue + theIntervalSize; curClassBreak = null; } //Now make the color ramp for the classes var colors = ColorFactory.Instance.GenerateColorsFromColorRamp(newColorizer.ColorRamp, numberofClasses); var c = 0; foreach (var cbreak in theClassBreaks) { //assign the generated colors to each class break in turn cbreak.Color = colors[c++]; } newColorizer.ClassBreaks = theClassBreaks; // Sets the newly created colorizer on the layer. basicRasterLayer.SetColorizer(newColorizer); }); }   The loop of manually creating class breaks is where things go sideways. The code above creates a new class break with the expected number of classes but, as the loop iterates, it adds whatever the "current" value is but it also updates all previous values in the class break collection with the current value's settings. So, at the end of the loop, all values in the class break object are the same. I'm at a loss to figure out what I'm doing wrong here. Help? Steve   ... View more

Now diving into the Pro SDK after so much time in the VBA & even VB.NET add-in sphere and I'm struggling with how to accomplish a specific task. I'm sure these are growing pains with C# but the Pro SDK isn't really doing me any favors about this either. I have a ProWindow which prompts the user to provide input parameters for tweaking the color ramp of a raster in the TOC. What I would like to do is populate a combo box with a list of the rasters in the TOC. I have the code to retrieve a list of rasters in the map:   var layerlist = MapView.Active.Map.GetLayersAsFlattenedList().OfType<BasicRasterLayer>();     but what I cannot figure out is how to insert this list of layers into the combo box. I've figured out how to find the event associated with the control but the process of how to populate it's data source is lost on me:   private void cboLayerList_Loaded(object sender, RoutedEventArgs e) { var layerlist = MapView.Active.Map.GetLayersAsFlattenedList().OfType<BasicRasterLayer>(); }     My control's name (cboLayerList) doesn't appear in the Intellisense suggestions so I'm at a loss as to how to hook into the control to populate the list of layers. There is a community sample about a combo box showing layers but I can't make the connection between that sample and how I'm trying to populate a combo box in my ProWindow. What am I missing (besides an understanding of C#)? Steve ... View more

Is there anyway to enforce a hierarchy on the results returned when using GetFeatures? For example, lets say I have a location with 3 features at a location- a road (line), a stream (line), and a bridge (point). Ideally, I'd like to have the results returned in the same order as my Table of Contents (bridge->road->stream) but, in reality, it's returning otherwise (road->bridge->stream). Thanks! Steve ...
