Datagrid behaviour and columns sorting

[jbv at mozik.fr]

Hi list,

I have a datagrid used as table with a behaviour on column 1 :
a button is being added in that column for each row.
When I click on other columns headers, the content of the
whole datagrid is sorted, except for column 1.
Is there a way to have the buttons in col 1 to be sorted
along with the contents of the other columns when clicking
on the headers ?

Thank you in advance.
Best regards,
jbv
