Introduction

The .NET framework makes it easy to event stubs by using operator +=.

Example

Consider the simple example below: 

  1. class SubscribeToEvents
  2. {
  3.     private rxButton _myButton;
  4.  
  5.     public SubscribeToEvents()
  6.     {
  7.         // Create a new button
  8.         _myButton = new rxButton();
  9.         // Subscribe to its 'onAction' event
  10.         _myButton.OnActionEvent += _myButton_OnActionEvent;
  11.     }
  12.  
  13.     // The event stub
  14.     void _myButton_OnActionEvent(IRibbonControl control)
  15.     {
  16.         throw new NotImplementedException();
  17.     }
  18. }

To insert the delegate stub (on line X) automatically you can do the following on line 8:

  1. type _myButton.OnActionEvent +=
  2. intellisense picks up and prompts you to press tab to insert the stub:
    InsertingEventStubCS.png
  3. Press tab twice. The delegate stub on line 14 will get inserted by visual studio.
