Elements and element properties

The IsFixed, IsHidden, IsHiddenWhenColumn, IsHiddenWhenRow, and Label properties can be specified for all elements. The default values for the IsFixed, IsHidden, IsHiddenWhenColumn, and IsHiddenWhenRow properties depend on the element; see the table below. For elements based on an MDM element, the Label property is the label of the MDM element, otherwise it will be empty.

The table below shows the remaining properties. For the AnalysisVariable, Decimals, Expression, Multiplier, Weight, and IncludeInBase properties, “Yes” indicates that a value can be set, while “No” indicates an error occurs when trying to set the property value. Note that “Yes” doesn’t mean the value has an effect – see the footnotes for more information. For the CalculationScope and Factor properties “Yes” indicates the property has an effect and “No” indicates that the property doesn’t apply to that element type. For IsUnweighted an error occurs when trying to set the property to False for the eBase and eUnweightedBase elements, otherwise a “No” in the column indicates IsUnweighted doesn’t apply to that element type.

For elements added from the metadata (i.e. via IElements.Add() and AddNewFromMdmVariable() ), the default value for the IsHidden property depends on the setting of the “Hidden” custom metadata property for the element. Some element types (added from the metadata) will always be hidden by default (IsHidden=True) as shown in the table below. For elements added via IElements.AddNew() and IElements.AddNewFromMdmVariable() the IsHidden property will always default to False.

For elements added from the metadata, the default value for the IsHiddenWhenColumn and IsHiddenWhenRow properties depend on the setting of the “HiddenWhenRow” and “HiddenWhenCol” custom metadata property for the element (respectively). If the custom property isn’t, or the element was added via IElements.AddNew() and IElements.AddNewFromMdmVariable(), the default value is always False.
