title: GridButtonColumn custom handler
body: <p>I have 4 tables that I've created using RadGrid. Each of them contains a list of items I have a title of and the id of. I want to have a column with a "Remove" link that will fire an event handler in which I will write code to remove this id from the db.</p>
  
  <p>Each of those tables has a separate table in the db so I need to know what table did fire the handler and what id does it correspond.</p>
  
  <p>Another small question is, what should I include so that visual studio recognize GridCommandEventArgs as a type?</p>
