Hello,

You will need some extra JS coding in afterShowForm event.

$opt["add_options"]["afterShowForm"] = 'function() { fill_add_form(); }';
..
$g->set_options($opt);

In this callback, you can read the values of last row of grid, e.g.

<script>
function fill_add_form()
{

// get all rows as array
var rows = $('#list1').getRowData();

// Now this last_row contains the object of last displayed row of grid. (not the last page's last row)
var last_row = rows[rows.length-1];

// Use jquery to set input fields data according to last_row object
jQuery("input[name=gender]").val( last_row.gender );

}
</script>

You can fill other rows in same manner.
