Example

The following example code shows how to call IXRCustomEvent::Raise in a custom method implementation in a data-source object. The custom method sets the global variable that reflects the current time on the device by using the string in the [in] parameter pstrCurrentTime. Then, it creates and populates an XRPropertyChangedCustomEventArgs, and raises the custom event, supplying it with the XRPropertyChangedCustomEventArgs event data.

#include <XamlRuntime.h>
 
WCHAR *m_pstrCurrentTime;
IXRCustomEvent<XRPropertyChangedCustomEventArgs, IXRPropertyBag> *m_pNotifyChangeEvent; 

void SetCurrentTime(WCHAR* pstrCurrentTime)
     {
          m_pstrCurrentTime = pstrCurrentTime;
          XRPropertyChangedCustomEventArgs args;
          args.PropertyName = L"CurrentTime";

          m_pNotifyChangeEvent->Raise(this, &args);
     }

.NET Framework Equivalent
