title: Add an individual column to cxGrid and use for selection purposes (checkbox)
body: <p>I do not want to add a database field in my actual database to use for selection purpose so I thought to use cxGrid's ability to add a separate field in the grid. I add the field,name it (select),change it's property to that of 'checkbox' but it seems I cant use it as it is not selectable in the grid. It behaves like read-only. How can I enable such thing ? Also,how do you later manipulate with such selected record in the grid ? (example: I want to insert that selected record under another date).</p>
