IXRVisualStateGroup::AddVisualStateChangedEventHandler (Windows Embedded CE 6.0)

1/6/2010

This method attaches a delegate to the VisualStateChanged event for this visual-state group. When the VisualStateChanged event occurs, this delegate will be invoked.

Syntax

virtual HRESULT STDMETHODCALLTYPE AddVisualStateChangedEventHandler(
    IXRDelegate<XRValueChangedEventArgs<IXRVisualState *>>* pDelegate
)= 0; 

Parameters

• pDelegate
  [in] IXRDelegate<ArgType> object that you want to attach to the VisualStateChanged event, which occurs when a control transitions into a different state.

  The CreateDelegate function provides an easy way to create this IXRDelegate object.

Return Value

Returns an HRESULT that indicates success or failure.

Returns XR_E_INVALID_OBJECT if pDelegate is not a Silverlight object.

Remarks

This event occurs after the control goes to a new state and after the VisualStateChanging event occurs.

Multiple delegates can be attached to the same event.

To remove this delegate from the VisualStateChanged event, call IXRVisualStateGroup::RemoveVisualStateChangedEventHandler.

.NET Framework Equivalent

None.
