title: devexpress ASPxGridView column problem
body: <p>I have an ASPXGRIDVIEW which is binded to an SQL query.
  I added to the grid an additional COLUMNCUSTOMBUTTON.
  But what happens is, that for all the rows it put a link there.
  I am trying to find a way to add to this column a link (button) ONLY to specific rows!</p>
  
  <p>I am unable to understand how to do it</p>
  
  <p>thanks</p>
