Checkbox on DataGrid

[RevList]

I have a datagrid that retrieves data from a MySQL database.  I want to
add a checkbox column to the grid so I have edited the template and added
the checkbox to the group and it displays just fine on the grid.  I can
check or uncheck the checkbox and the appropriate hilite is set.  However,
when I scroll the datagrid, the checkbox appears in the same location on
the next scroll screen too.  I am missing something.
