Working with Rule Application Metadata

// System and user-defined attributes
string attributeValue = ruleSession.GetRuleApplicationDef().Attributes["MyAttribute"];

// Categories defined in the rule application
CategoryDefCollection categories = ruleSession.GetRuleApplicationDef().Categories;

// Getting name of first category in collection
string catalogName = categories[0].Name;

// Getting DataElementDef
DataElementDef dataElementDef = (DataElementDef)ruleSession.GetRuleApplicationDef().DataElements["MyInlineTable"];

// Iterate through the entities for the rule application
foreach (EntityDef entityDef in ruleSession.GetRuleApplicationDef().Entities)
{
  Console.WriteLine(entityDef.Name);
}

// Get EntityDef from Entity
EntityDef entityDef = entity.GetDef();

// Get FieldDef from Field
FieldDef fieldDef = field.GetDef();

// Get CollectionDef from Collection, assigned to FieldDef
FieldDef collectionDef = collection.GetDef();

// Get RuleSetDef from RuleSet
RuleSetDef ruleSetDef = (RuleSetDef)ruleSet.GetDef();

// Get RuleElementDef from RuleElement, getting first child element in this example
RuleElementDef ruleElementDef = ruleSet.RuleElements[0].GetDef();

// Iterate through fields in an entity
foreach (FieldDef fieldDef in invoiceEntity.GetDef().Fields)
{
if (fieldDef.IsCalculated)
      // Display the expression if a calculation
      Console.WriteLine(fieldDef.Calc.FormulaText);

 if (fieldDef.IsAnEntityDataType)
      // Display the referenced entity if a child entity field
      Console.WriteLine(fieldDef.DataTypeEntityName);
}

// Get data type
string dataType = fieldDef.DataType.ToString();

// Get default value
string defaultValue = fieldDef.DefaultValue.ToString();

// Get Attributes
ICollection attributes = fieldDef.Attributes.Values;

// Get assigned categories
ICollection assigned = fieldDef.AssignedCategories;

// Iterate through the rule sets on an entity
foreach (RuleSet ruleSet in invoiceEntity.RuleSets)
{
  // Cast into a RuleSetDef
 RuleSetDef ruleSetDef = (RuleSetDef)ruleSet.GetDef();
  // See if this is an active explicit ruleset
  if (ruleSetDef.FireMode == RuleSetFireMode.Explicit && ruleSetDef.IsActive)
   {
      Console.WriteLine(ruleSet.Name);
   }
}

// Retrieve an attribute defined on an entity
Console.WriteLine(entityDef.Attributes.Default["MyAttribute"]);

if (fieldDef.Attributes != null && fieldDef.Attributes.Count > 0)
{
  foreach (XmlSerializableStringDictionary.XmlSerializableStringDictionaryItem attributeItem
in fieldDef.Attributes.Default)
   {
      Console.WriteLine(attributeItem.Key + ":" + attributeItem.Value);

foreach (ValueListItem valueListItem in valueList)
{
  // Add the list item value to the combobox
   comboBox.Items.Add(valueListItem);
   comboBox.DisplayMemberPath = "Value";
}

// Get value list using the session’s DataManager
ValueList myList = ruleSession.Data.GetValueList("StandAloneValueList");

// Tell combo box what field to display to the end user
comboBox.DisplayMemberPath = "DisplayText";

// Add the item to the combo box
foreach (ValueListItem item in myList)
{
    comboBox.Items.Add(item);              
}
