	IColumnDataAttribute, IDataAttribute
where TObject : DomainObject

Public Class ColumnDataAttribute(Of TObject As DomainObject, TValue)
	Inherits DataAttribute(Of TObject, TValue)
	Implements IColumnDataAttribute, IDataAttribute

generic<typename TObject, typename TValue>
where TObject : DomainObject

Type Parameters

TObject: The type of the domain object, which contains the attribute.
TValue: The type of the stored data

The ColumnDataAttributeTObject, TValue type exposes the following members.

Properties

	Name	Description
	BaseInfo	Gets the base information. (Inherited from DataAttributeBaseTObject.)
	ColumnName	The underlying data column name
	DefaultValue	Gets the default value. (Inherited from DataAttributeBaseTObject.)
	Expressions	Gets the recalc expression. (Inherited from DataAttributeBaseTObject.)
	GetRow	The delegate that returns the buffer row, containing the storage column
	IsBlob	Gets a value indicating whether this attribute data is BLOB. (Inherited from DataAttributeBaseTObject.)
	IsPersistent	Gets a value indicating whether this attribute is persistent. Only persistent attributes support track changes. (Inherited from DataAttributeBaseTObject.)
	LocalizedName	Gets the name of the attribute in the current UI culture. (Inherited from DataAttributeBaseTObject.)
	Name	Gets the name of the data Property (Inherited from DataAttributeBaseTObject.)
	PrimitiveValueType	Gets the primitive type or null. Used in public APIs to represent a complex value as a primitive value. (Inherited from DataAttributeBaseTObject.)
	ReadOnly	Is the data attribute read-only for user editing. (Inherited from DataAttributeBaseTObject.)
	SupportsGet	Gets a value indicating whether the attribute supports getting a value. (Inherited from DataAttributeBaseTObject.)
	SupportsSet	Gets a value indicating whether the attribute supports setting a value. (Inherited from DataAttributeBaseTObject.)
	TableName	The table used to persist and locally store the objects data
	ValueType	Gets the value of the data attribute for the specified domain object (Inherited from DataAttributeTObject, TValue.)

Methods

	Name	Description
	FilterBy	Creates and returns filter condition for the data attribute (Overrides DataAttributeBaseTObjectFilterBy(ComparisonType, Object, Boolean).)
	GetComplexTypeAccessor	Gets the complex type value accessor or null if the attribute does not support it. Complex type values are frequently used in Entity Data Models. (Inherited from DataAttributeBaseTObject.)
	GetDisplayValueAccessor	Gets the display text accessor or null if the attribute does not support it. The display value is localized in the current thread culture and is suitable for displaying and modification by end users. (Overrides DataAttributeBaseTObjectGetDisplayValueAccessor(String).)
	GetInvariantStringAccessor	Gets the culture-neutral text value accessor or null if the attribute does not support it. The text value represents the values for import/export to text files or streams. (Overrides DataAttributeBaseTObjectGetInvariantStringAccessor.)
	GetPrimitiveValueAccessor	Gets the primitive value accessor or null if the attribute does not support it. Used in public APIs to represent a complex value as a primitive value. (Inherited from DataAttributeBaseTObject.)
	GetUntypedValue	Gets the value of the data attribute for the specified domain object (Inherited from DataAttributeBaseTObject.)
	GetUntypedValueForRow	Gets the value of the attribute from any compatible buffer row
	GetValue	Gets the value of the data attribute for the specified domain object (Inherited from DataAttributeTObject, TValue.)
	HasValue	Determines whether the specified object has value for the data attribute. (Inherited from DataAttributeBaseTObject.)
	OnDataAttributeChanged	Raises the DataAttributeChanged event. (Inherited from DataAttributeBaseTObject.)
	Prepare	Performs attribute-specific work to prepare the attribute. For example calculated attributes must be compiled. Called by the system after the attribute is added to the repository. (Inherited from DataAttributeBaseTObject.)
	SetDefaultValue	Sets the attribute to its default value. (Inherited from DataAttributeBaseTObject.)
	SetUntypedValue	Sets the value of the data attribute for the specified entity object (Inherited from DataAttributeBaseTObject.)
	SetUntypedValueForRowCore	Sets the value of the attribute for any compatible buffer row
	SetValue	Sets the value of the data attribute for the specified domain object (Inherited from DataAttributeTObject, TValue.)
	ShouldRecalculateLateDefault	Returns true if the attribute should be recalculated for the specified object. (Inherited from DataAttributeBaseTObject.)
	ToString	Returns a String that represents this instance. (Overrides ObjectToString.)

Events

	Name	Description
	DataAttributeChanged	The data attribute changed event. Fired after the data attribute changes for an object. (Inherited from DataAttributeBaseTObject.)

Extension Methods

	Name	Description
	GetUntypedValueAccessor	Gets the untyped value accessor. (Defined by IDataAttributeExtensions.)
	IsNull	Determines whether value of the attribute of the specified object is null. (Defined by IDataAttributeExtensions.)
