Hi,

Not sure if you were able to resolve your issue or not. Without looking at your data it's hard to tell what's going wrong. But I noticed one small thing in your code when you select. You already have a geoElement (sceneLayer.SelectFeature((Feature)geoElement);) and you can try getting the attribute using the same object rather than trying to get it again?

In any case, if it hasn't resolved for you, it would help if you can share a small sample dataset and I can try it out on my end.

Hi KoushikHajra

Thank you for your valuable response.

I cannot able to get the object attributes using following code.

string currentAttributeValue = _selectedFeature.Attributes[AttributeFieldName].ToString();

I needs to get the  attributes values in WPF application, which is given by City Engine Object Attributes.

see following figure

My code is below

ArcGISSceneLayer sceneLayer = new ArcGISSceneLayer();

foreach (var sl in MySceneView.Scene.OperationalLayers)
{
if (!string.IsNullOrEmpty(sl.Id))
{
sceneLayer = (ArcGISSceneLayer)sl;

sceneLayer.ClearSelection();

IdentifyLayerResult identifyResult = await MySceneView.IdentifyLayerAsync(sceneLayer, e.Position, 1, false, 1);

IReadOnlyList<GeoElement> geoElements = identifyResult.GeoElements;

if (geoElements.Any())
{
GeoElement geoElement = geoElements.FirstOrDefault();
if (geoElement != null)
{
sceneLayer.SelectFeature((Feature)geoElement);

var _selectedFeature = (ArcGISFeature)identifyResult.GeoElements.First();

string currentAttributeValue = _selectedFeature.Attributes["City"].ToString();
}
}
}
}

above code raise the following exception

The given key 'City' was not present in the dictionary.

Please give us advice
