Methods

View Source

ConvertDbToString(IPropertyType, Object)

Converts a property value to a string.

Declaration

public virtual string ConvertDbToString(IPropertyType propertyType, object value)

Parameters

Type	Name	Description
IPropertyType	propertyType
System.Object	value

Returns

Type	Description
System.String

View Source

ConvertDbToXml(IProperty, Boolean)

Converts a property to Xml fragments.

Declaration

public IEnumerable<XElement> ConvertDbToXml(IProperty property, bool published)

Parameters

Type	Name	Description
IProperty	property
System.Boolean	published

Returns

Type	Description
IEnumerable<System.Xml.Linq.XElement>

View Source

ConvertDbToXml(IPropertyType, Object)

Converts a property value to an Xml fragment.

Declaration

public XNode ConvertDbToXml(IPropertyType propertyType, object value)

Parameters

Type	Name	Description
IPropertyType	propertyType
System.Object	value

Returns

Type	Description
System.Xml.Linq.XNode

Remarks

By default, this returns the value of ConvertDbToString but ensures that if the db value type is NVarchar or NText, the value is returned as a CDATA fragment - else it's a Text fragment.

Returns an XText or XCData instance which must be wrapped in a element.

If the value is empty we will not return as CDATA since that will just take up more space in the file.

View Source

FromEditor(ContentPropertyData, Object)

A method to deserialize the string value that has been saved in the content editor to an object to be stored in the database.

Declaration

public virtual object FromEditor(ContentPropertyData editorValue, object currentValue)

Parameters

Type	Name	Description
ContentPropertyData	editorValue	The value returned by the editor.
System.Object	currentValue	The current value that has been persisted to the database for this editor. This value may be useful for how the value then get's deserialized again to be re-persisted. In most cases it will probably not be used.

Returns

Type	Description
System.Object	The value that gets persisted to the database.

Remarks

By default this will attempt to automatically convert the string value to the value type supplied by ValueType. If overridden then the object returned must match the type supplied in the ValueType, otherwise persisting the value to the DB will fail when it tries to validate the value type.

View Source

ToEditor(IProperty, String, String)

A method used to format the database value to a value that can be used by the editor.

Declaration

public virtual object ToEditor(IProperty property, string culture = null, string segment = null)

Parameters

Type	Name	Description
IProperty	property	The property.
System.String	culture	The culture.
System.String	segment	The segment.

Returns

Type	Description
System.Object

Remarks

The object returned will automatically be serialized into JSON notation. For most property editors the value returned is probably just a string, but in some cases a JSON structure will be returned.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	ValueType was out of range.

View Source

Validate(Object, Boolean, String)

Declaration

System.String	format	A specific format (regex) that the property value must respect.

Returns
