Hello,

Detail grid shows relative data when we select some record in master.
You can however display blank (at start) by specifying some false where condition.

e.g.

// and use in sql for filteration
$grid->select_command = "SELECT id,client_id,invdate,amount,tax,total,'$company' as 'company' FROM invheader WHERE client_id = $cid";

Here $cid is passed when master is selected. You can set

if (empty($cid)) $cid = -1;

It will result in no records for initial display of detail grid.
