Constructors

PropertyValue(PropertyEntry)

Initializes a new instance of the PropertyValue class with the parent property set to a specified PropertyEntry object.

Properties

CanConvertFromString

When implemented in a derived class, gets a value that indicates whether Value can be converted from a string.

CatchExceptions

Gets a value that indicates whether exceptions thrown during property value getting and setting should be caught or should be propagated directly to the caller.

Collection

When implemented in a derived class, gets a collection of PropertyValue instances that correspond to items in a collection when IsCollection verifies that the property is a collection.

HasSubProperties

When implemented in a derived class, gets a value that indicates whether the type of this property supports sub-properties.

IsCollection

When implemented in a derived class, gets a value that indicates whether this PropertyValue is a collection.

IsDefaultValue

When implemented in a derived class, gets a value that indicates whether the Value is the default value for the property.

IsMixedValue

When implemented in a derived class, gets a value that indicates whether multiple objects contain this property and have different values.

ParentProperty

Gets the parent PropertyEntry when the property implementation occurs in a host environment.

Source

When implemented in a derived class, gets a PropertyValueSource object that contains information about where this property value is coming from.

StringValue

Gets or sets a Value as a String.

SubProperties

When implemented in a derived class, gets a collection of sub-properties as PropertyEntry instances.

Value

Gets or sets a property value in the underlying collection of property data.

Methods

ClearValue()

When implemented in a derived class, clears the PropertyValue so that it is unset.

ConvertStringToValue(String)

When implemented in a derived class, converts the specified StringValue to a Value.

ConvertValueToString(Object)

When implemented in a derived class, converts the specified Value to a StringValue.

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
GetValueCore()

When implemented in a derived class, returns a Value.

MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
NotifyRootValueChanged()

Raises the RootValueChanged event when the underlying value type is changed externally, as on the design surface.

NotifySubPropertyChanged()

Raises the SubPropertyChanged event when one of the sub-properties of this property has changed.

OnPropertyChanged(PropertyChangedEventArgs)

Raises the PropertyChanged event with the specified PropertyChangedEventArgs objects.

OnPropertyChanged(String)

Raises the PropertyChanged event that uses the name of the property that changed.

OnPropertyValueException(PropertyValueExceptionEventArgs)

Default implementation that raises the PropertyValueException event when PropertyValue properties experience failure getting or setting values in the underlying collection of data.

SetValueCore(Object)

When implemented in a derived class, sets the Value.

ToString()

Returns a string that represents the current object.

(Inherited from Object)
ValidateValue(Object)

When implemented in a derived class, throws an exception if verification of the specified value object shows it to be invalid.

Events

PropertyChanged

Occurs when properties or sub-properties of the PropertyValue object has changed.

PropertyValueException

Event used by host implementations for error handling.

RootValueChanged

Occurs when the Value or StringValue property is updated as a result of the PropertyValue value being changed.

SubPropertyChanged

Occurs when sub-properties are updated as a result of the PropertyValue being changed.
