ArcGIS.Desktop.Mapping Namespace / BuildingSceneLayer Class / GetAvailableFieldsAndValues Method
Example Version

GetAvailableFieldsAndValues Method
Gets all available fields and their corresponding values for a building scene layer. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
public Dictionary<string,List<string>> GetAvailableFieldsAndValues()

Return Value

Dictionary{System.String, List{System.String}}"/>
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Remarks
Any combination of the available fields paired with one or more of their corresponding values can be added to the FilterBlockDefinition.SelectedValues for a given filter block
Use GetAvailableFieldsAndValues to determine what the available fields and values are that can be used for a given BuildingSceneLayer
Example
Query Building Scene Layer for available Types and Values
//Must be called on the MCT
//Retrieve the complete set of types and values for the building scene
//var bsl = ...;
//At 2.x - var dict = bsl.QueryAvailableFieldsAndValues();
var dict = bsl.GetAvailableFieldsAndValues();

//get a list of existing disciplines
var disciplines = dict.SingleOrDefault(
         kvp => kvp.Key == "Discipline").Value ?? new List<string>();

//get a list of existing categories
var categories = dict.SingleOrDefault(
         kvp => kvp.Key == "Category").Value ?? new List<string>();

//get a list of existing floors or "levels"
var floors = dict.SingleOrDefault(
         kvp => kvp.Key == "BldgLevel").Value ?? new List<string>();
Create a Filter using Building Level and Category
//Must be called on the MCT

//refer to "Query Building Scene Layer for available Types and Values"
//...
//var bsl = ...;
//At 2.x
//var dict = bsl.QueryAvailableFieldsAndValues();

//var dict = bsl.GetAvailableFieldsAndValues();
//var categories = dict.SingleOrDefault(kvp => kvp.Key == "Category").Value;
//var floors = dict.SingleOrDefault(kvp => kvp.Key == "BldgLevel").Value;

//Make a new filter definition
var fd = new FilterDefinition()
{
  Name = "Floor and Category Filter",
  Description = "Example filter",
};
//Set up the values for the filter
var filtervals = new Dictionary<string, List<string>>();
filtervals.Add("BldgLevel", new List<string>() { floors[0] });
var category_vals = categories.Where(v => v == "Walls" || v == "Stairs").ToList() ?? new List<string>();
if (category_vals.Count() > 0)
{
  filtervals.Add("Category", category_vals);
}
//Create a solid block (other option is "Wireframe")
var fdef = new FilterBlockDefinition()
{
  FilterBlockMode = Object3DRenderingMode.None,
  Title = "Solid Filter",
  SelectedValues = filtervals//Floor and Category
};
//Apply the block
fd.FilterBlockDefinitions = new List<FilterBlockDefinition>() { fdef };
//Add the filter definition to the layer
//At 2.x - bsl.SetFilter(fd);
bsl.UpdateFilter(fd);
//Set it active. The ID is auto-generated
bsl.SetActiveFilter(fd.ID);
