Exceptions

Exception	Condition

ValidationException	The propertyName is invalid.
NotAuthorizedException	The caller is not authorized to perform this operation.
EntityAlreadyExistsException	The propertyName already exists in the catalog system.

Remarks

This method creates a property in the catalog system and returns a CatalogProperty object. You can use the CatalogProperty object to set various attributes on the property and add enumeration values to the property if the data type of the property is Enumeration. You should call the Save method to save the changes made to the CatalogProperty object to the catalog system. You do not need to call the Save method if you create the property but do not change its attributes. The catalog system supports the following data types:

The propertyName should:

Not be nullNothingnullptra null reference (Nothing in Visual Basic) or blank.
Not exceed 100 characters.
Not contain the .,"[] characters.
Not begin with a digit.

If the dataType is String then the maxLength should be between 1 and 4000. A property of Enumeration data type will be created with a maximum length of 128 characters and a property of FilePath data type will be created with a maximum length of 256 characters. For all other data types the maxLength will be ignored.

Examples

This example shows how to create a multilingual string property and set its DisplayName and IsFreeTextSearchable attributes.

private void CreateMultilingualProperty(CatalogContext catalogContext)
{
  CatalogProperty catalogProperty = catalogContext.CreateProperty("StringProperty", CatalogDataType.String, 100);
  catalogProperty.Information.CatalogProperties[0].LanguageSensitive = true;
  catalogProperty.Information.CatalogProperties[0].DisplayName = "Property Displayname";
  catalogProperty.Information.CatalogProperties[0].IsFreeTextSearchable = true;
  catalogProperty.Save();
}
