给控件增添 鼠标单击事件

给控件添加 鼠标单击事件
我这里有一个控件  DevExpress.XtraNavBar.NavBarItem
我对它进行了重写  public partial class DeNavBarItem : DevExpress.XtraNavBar.NavBarItem
     但它本身没有单击事件，我想给他添加些 鼠标事件,如获得焦点，和失去焦点事件，鼠标单击、等 
该怎样做，有谁做过没？ 
[解决办法]
控件开发自定义事件
如public   event   EventHandler   TextChanged; 
protected   virtual   void   OnTextChanged() 
{ 
if(this.TextChanged!=null) 
this.TextChanged(this,EventArgs.Empty); 
} 

自定义事件
[解决办法]
最近也在用这套
实际上获取NavBarItem的焦点，单击等事件没有必要。
因为可以在NavBarControl 类中处理。


另外NavBarItem是支持单击事件的，事件名为
 LinkClicked和 LinkPressed 
[解决办法]
通过NavBarControl 类来处理
