virtual void OnDrawNode(System::Windows::Forms::DrawTreeNodeEventArgs ^ e);protected virtual void OnDrawNode (System.Windows.Forms.DrawTreeNodeEventArgs e);abstract member OnDrawNode : System.Windows.Forms.DrawTreeNodeEventArgs -> unit

A DrawTreeNodeEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnDrawNode method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnDrawNode(DrawTreeNodeEventArgs) in a derived class, be sure to call the base class's OnDrawNode(DrawTreeNodeEventArgs) method so that registered delegates receive the event.
