The event data.

The OnMouseLeftButtonDown method is called before any event handler for the MouseLeftButtonDown is called. This method allows derived classes to handle the MouseLeftButtonDown event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

This implementation marks the MouseLeftButtonDown event as handled by setting the Handled property of the event data to true. In addition, this implementation sets the IsDropDownOpen property to true.
