IXRDependencyObject::SetAttachedProperty(const WCHAR*, const WCHAR*, bool) (Compact 2013)

3/28/2014

This method sets the value of the specified attached property if it has a Boolean type.

Syntax

virtual HRESULT STDMETHODCALLTYPE SetAttachedProperty(
    __in const WCHAR* pName,
    __in_opt const WCHAR* pNamespace,
    __in bool Value
) = 0;

Parameters

• pName
  [in] Pointer to a string that contains the name of the attached property that you want to set for this object.

• pNamespace
  [in, optional] Pointer to a string that contains the name of the namespace in which to look. Use this parameter to access an attached property of a custom control. If pNamespace is null, this method looks in the current default namespace.

• Value
  [in] New value to set for the property that you specified in pName.

Return Value

Returns XR_E_INVALID_PROPERTY if this method was unable to locate the property requested. Otherwise, returns an HRESULT that indicates success or failure.

Remarks

Attached properties are part of the XAML language. You can set an attached property on C++ objects or XAML elements.

You can use this method to set the value of attached properties in XAML for Windows Embedded, such as Canvas.Left. In this case, the attached property name consists of the owner class name for the attached property, a dot, and the attached property name ("ownerType.propertyName"). You can also use this method to set the value of a custom attached property that you created and registered for a user-defined control.

Example

The following lines of C++ code demonstrate the correct syntax for using this method to set the Selector.IsSelected attached property for the inheriting IXRUIElement object:

bool Value = 0;
myElement->SetAttachedProperty(L"Selector.IsSelected", NULL, Value);

.NET Framework Equivalent

System.Windows.DependencyObject.SetValue
