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

  • Artigo

3/28/2014

This method sets the value of the specified attached property if the attached property has a 32-bit integer type or if the attached property has an enumerated type that is also represented by an integer.

Syntax

virtual HRESULT STDMETHODCALLTYPE SetAttachedProperty(
    __in const WCHAR* pName,
    __in_opt const WCHAR* pNamespace,
    __in int 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] An integer value that reflects the 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

You can use this method to set the value of attached properties in XAML for Windows Embedded, such as Canvas.Left, or to set the value of a custom attached property that you created and registered for a user-defined control. 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").

Example

The following lines of C++ code demonstrate the correct syntax for using this method to set the ScrollViewer.HorizontalScrollBarVisibility attached property for the inheriting IXRUIElement object by casting it to its integer value:

Important

For readability, the following code example does not contain security checking or error handling. Do not use the following code in a production environment.

XRScrollBarVisibility Value = XRScrollBarVisibility_Visible;
myElement->SetAttachedProperty(L"ScrollViewer.HorizontalScrollBarVisibility" , NULL, (int)Value);
