How to raise an attached event in wpf?

Question

How can I raise a DataObject.Pasting event from my code?

Answer 1

You can raise any event on any UIElementusing the method RaiseEvent(). Just create the appropriate event arguments for the handler and go to RaiseEvent().

var args = new DataObjectPastingEventArgs(dataObject, isDragDrop, formatToApply)
{
    Source = this,
    RoutedEvent = DataObject.PastingEvent //set the event here
};
element.RaiseEvent(args);

Answer 2

You need to call RaiseEvent in the corresponding UIElement, passing RoutedEventArgs with the RoutedEvent parameter set to DataObject.Pasting.
