To partially answer my own question, you can implement a SortedDictionary on the results of the mapTool click to at least create a sorted list based on your Table of Contents. Dictionary<MapMember, List<long>> features = new Dictionary<MapMember, List<long>>(); features = mapView.GetFeatures(geometry).ToDictionary(); Dictionary<int, string> theHitList = new Dictionary<int, string>(); var counter = 0; foreach (var feature in features) { theHitList.Add(counter, feature.Key.Name); counter++; } var theLayerName = getTopLayer(theHitList, features.First().Key.Map);   The getTopLayer function with the SortedDictionary is in this function:   private static string getTopLayer(Dictionary<int,string> clickList, Map theMap) { var layers = MapView.Active.Map.GetLayersAsFlattenedList(); // MapView.Active.Map.Layers.Where(layer => layer is FeatureLayer); SortedDictionary<int, string> sortedLayerList = new SortedDictionary<int, string>(); foreach (var layer in clickList) { var curLayerName = layer.Value; for (int i = 0; i < layers.Count; i++) { if (layers[i].Name == curLayerName) { sortedLayerList.Add(i, layers[i].Name); break; } } } return sortedLayerList.First().Value; }   I'm still learning C# so I'm sure there are more elegant and efficient ways to do this. In my use case, I'm labelling so I was really only concerned with the topmost layer that was clicked on using the mapTool. Nonetheless, the sortedDictionary is the mechanism to sort the information. all you do is just walk through the layers in the TOC, and add the clicked features' layer and TOC position number. So far, this has worked in my testing so I'm happy enough with this approach. Steve ... View more

You could probably do this by tweaking the underlying JSON of your webmap using ArcGIS Assistant. What I'd suggest is add a hosted layer and apply the "in the last 5 years" filter to it. Now, log into ArcGIS Assistant, navigate to the Web Map, and inspect its JSON. The layer information will be in the Data grouping. Find the layer that uses that filter and then you should see an entry for DefintionExpression. That section of JSON will look something like this: Just copy the text of the definition expression, tweak it to apply to your layer of interest, and then paste it into that layer's definitionExpression property. Since you're directly editing your web map, I would highly suggest making a copy of the map and testing this out in the web map copy first. Make sure it works before you alter your actual web map. ... View more
