DependencyObject.GetValueBase Method

.NET Framework 4

Provides access to the bound object of a DependencyProperty and bypasses the GetValue override.

Namespace: System.Workflow.ComponentModel
Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)

Syntax

C++

Copy

public Object GetValueBase(
	DependencyProperty dependencyProperty
)

Parameters

dependencyProperty: Type: System.Workflow.ComponentModel.DependencyProperty
The DependencyProperty to get the value of.

Return Value

Type: System.Object
The bound object of a DependencyProperty. This bypasses the GetValue override.

Exceptions

Exception	Condition
ArgumentNullException	dependencyProperty is a null reference (Nothing in Visual Basic).

Remarks

This method is useful inside the GetValue override implementation. Typically, the GetValue override code invokes the GetValueBase, and then adds additional code.

For implementing the GetValue override, PropertyMetadata can be used in Register/RegisterAttached calls.
