Public Function GetValueBase (dependencyProperty As DependencyProperty) As Object

Parameters

dependencyProperty: DependencyProperty

The DependencyProperty to get the value of.

Returns

Object

The bound object of a DependencyProperty. This bypasses the GetValue(DependencyProperty) override.

Exceptions

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.
