Thanks for the tip.

Can I also disable one column on a button click.
Say for example the grid is grdtest and has two columns
clmcode and clmname

Now on a button click if I want to disable clmcode how can I do that
the following code is not working
thisform.grdtest.clmcode.readonly = .t.
or
thisform.grdtest.clmcode.txtcode.readonly = .t.

Pl. help. Thanks once again.

Regards
