Adding/Editing Definition Query on ImageServiceLayer silently fails

Hello. I am loading an ImageServiceLayer from a URL. Through the UI, I can add a Definition Query to it.

Through the SDK, I can see the previously created Definition Query. But I cannot add, edit or remove it in any way.

ImageServiceLayer ISL = null; List<Layer> layers = map.GetLayersAsFlattenedList().ToList(); foreach (var layer in layers) { if (layer is ImageServiceLayer) { if (layer.Name == "ImageLayer") ISL = layer as ImageServiceLayer; } } if (ISL == null) { Uri uri = new Uri("..."); ISL = LayerFactory.Instance.CreateLayer(uri, map, 0) as ImageServiceLayer; } // If I have set a Definition Query through ArcGIS Pro UI, I can read it using ISL.DefinitionQuery DefinitionQuery dq = new DefinitionQuery("QueryName", "OBJECTID = 5"); ISL.InsertDefinitionQuery(dq, true); // This does nothing.

I have tried a bunch of stuff but nothing seems to work. I can't edit an existing Definition Query, I can't remove it, I can't add a new one. Am I doing something wrong, or is it bugged?

I see the same issue. Thanks for reporting this one. I have submitted an issue to the development team that owns this functionality.

Thanks!

Will this be fixed in the next version?

I can post back to this thread if I have an update on this issue. But here is a workaround to access and set queries. You can access the CIM Definition of the ImageService Layer - this will give you access to the definition queries. Here is a code snippet that shows you how to do this.

var definition = imageServiceLayer.GetDefinition() as CIMImageServiceLayer; var featureTable = definition.FeatureTable; //This is a list of all the definition queries var defnFilterChoices = featureTable.DefinitionFilterChoices; //Iterate through the definition queries foreach (var defnFilterChoice in defnFilterChoices) { //access the definition queries here var cimDefinitionFilter = defnFilterChoice as CIMDefinitionFilter; var queryName = cimDefinitionFilter.Name; var expression = cimDefinitionFilter.DefinitionExpression; } //To activate a definition query featureTable.DefinitionExpression = "Name = '76264301'"; //example featureTable.DefinitionExpressionName = "Query 1"; //example //Set defintion imageServiceLayer.SetDefinition(definition);
