title: Hide a column with buttons in cxGrid
body: <p>I have a cxGrid with a columne that holds some buttons and I would like to be able to hide this column
  The reason for this is that I use the same grid for printing that I use for input. But there are some columns that isn't wanted on the report.
  I know how to hide a column by using GetColumnByFieldName but I can't figure out how to do it with the button column since it has no fieldname</p>
