PropertyValue Class
.NET Framework 4.5
Maintains a data model for the value of a property in the property grid.
Namespace:
System.Activities.Presentation.PropertyEditing
Assembly: System.Activities.Presentation (in System.Activities.Presentation.dll)
The PropertyValue type exposes the following members.
| Name | Description | |
|---|---|---|
 | PropertyValue | Initializes a new instance of the PropertyValue class with the parent property set to a specified PropertyEntry object. |
| Name | Description | |
|---|---|---|
 | 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. |
| Name | Description | |
|---|---|---|
 | ClearValue | When implemented in a derived class, clears the PropertyValue so that it is unset. |
| ConvertStringToValue | When implemented in a derived class, converts the specified StringValue to a Value. |
| ConvertValueToString | 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.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (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 | Default implementation that raises the PropertyValueException event when PropertyValue properties experience failure getting or setting values in the underlying collection of data. |
| SetValueCore | When implemented in a derived class, sets the Value. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| ValidateValue | When implemented in a derived class, throws an exception if verification of the specified value object shows it to be invalid. |
| Name | Description | |
|---|---|---|
 | 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. |
