ModelProperty Class

Definition

Namespace:

System.Activities.Presentation.Model

Assembly:

System.Activities.Presentation.dll

A ModelProperty represents a property on a ModelItem. Model properties are associated with an instance of an item, which allows them to have simple Value get/set properties instead of using the more cumbersome GetValue/SetValue mechanism of PropertyDescriptor.

Remarks

The value of a ModelProperty may come from a locally set value, or it may be inherited from somewhere higher up in the element hierarchy. Use the Source property of the value returned by Value to determine the source of the property value.

Constructors

ModelProperty()

Creates a new ModelProperty.

Properties

AttachedOwnerType	Returns the type that defines this property if IsAttached returns true; otherwise, returns null.
Attributes	Returns the attributes declared on this property.
Collection	Returns Value cast as a ModelItemCollection.
ComputedValue	Returns the currently computed value for this property. Setting a value on this property is the same as calling SetValue(Object), but can be used in data binding expressions.
Converter	Returns the type converter to use with this property.
DefaultValue	Returns the default value for this property. If the property does not define a default value, this will return null.
Dictionary	Returns Value cast as a ModelItemDictionary. If the property value is not a dictionary, this property will return null.
IsAttached	Determines whether the property represents an attached property from a different type.
IsBrowsable	Determines whether the property can be shown in a property window.
IsCollection	Determines whether the value contained in the property is a ModelItemCollection.
IsDictionary	Determines whether the value contained in the property is a ModelItemDictionary.
IsReadOnly	Determines whether the property is read only.
IsSet	Determines whether the value of the property is set locally.
Name	Gets the name of this property.
Parent	Returns the parent of this property.
PropertyType	Returns the data type of the property.
Value	Returns the value set into this property.

Methods

ClearValue()	Clears the local value for the property.
Equals(Object)	Determines the equality for properties. Properties are equal if they have the same name and parent.
GetHashCode()	Serves as a hash function for a ModelProperty.
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
SetValue(Object)	Sets a local value on a property.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Operators

Equality(ModelProperty, ModelProperty)	Determines whether the properties are equal. Properties are equal if they have the same name and parent.
Inequality(ModelProperty, ModelProperty)	Determines whether the properties are unequal. Properties are equal if they have the same name and parent.
