Hi abu,  here looking to have the following.

In grid1 i have next settings:

$opt[“detail_grid_id”] = “list2”;
$opt[“subgridparams”] = “id,idserie”;

in grid2 have a column with:

$col = array();
$col[“title”] = “SubSerie”;
$col[“name”] = “idsubs”;
$col[“formatter”] = “select”;
$str2 = $grid2->get_dropdown_values(“select id as k, concat(clave,concat(‘-‘,descrip)) as v from subseries where client_id=”.$IDSERIE);
$col[“edittype”]=”select”; $col[“editoptions”] = array(“value” => $str2, “separator” => “:”, “delimiter” => “;”);
$cols2[] = $col;

obviously the use of $IDSERIE in the source of the dropdown list doesn’t work….
