This method registers an attached property for a user-defined control.

Syntax

virtual HRESULT STDMETHODCALLTYPE RegisterAttachedProperty(
  __in        LPCWCHAR                        pPropertyName,
  __in        VALUE_TYPE                      vType,
  __in_opt    UINT                            objectId,
  __in        XRDependencyPropertyMetaData*   pMetaData,
  __out_opt   DEPENDENCY_PROPERTY_ID*    pDependencyPropertyIdentifier
) = 0;

Parameters

pPropertyName
[in] Pointer to a string that indicates the name of the attached property to register.

vType
[in] VALUE_TYPE enumerated value that indicates the type of property value, such as a string, integer, or object.

objectId
[in] Integer value that represents the control ID, which is retrieved by IXRApplication::RegisterControl or XRCustomUserControlImpl::ControlID.

pMetaData
[in] XRDependencyPropertyMetaData structure that contains metadata for the attached property.

pDependencyPropertyIdentifier
[out, optional] A value that represents the identifier of the dependency property of a custom control. A DEPENDENCY_PROPERTY_ID value is returned when you call IXRApplication::RegisterDependencyProperty to register a dependency property after you have called IXRApplication::RegisterControl to register your custom control.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

If you register an attached property, other objects can access its value by calling either IXRDependencyObject::GetAttachedProperty or IXRDependencyObject::SetAttachedProperty and referencing it by using the object.propertyname syntax.

Objects that inherit from IXRDependencyObject can support attached properties.
