I don't understand your query completely, I am answering what i guess the query is.

You can virtual column for custom data in grid, and fill that column using filter_display event.
e.g.

// virtual column to show grid

$col = array();
$col["title"] = "Id";
$col["name"] = "vid";
$col["width"] = "400";
$col["hidden"] = true;
$cols[] = $col;

$e["on_data_display"] = array("filter_display", null, true);
$g->set_events($e);

function filter_display($data)
{
$i=1;
foreach($data["params"] as &$d)
{
$d["vid"] = $i++;
}
}

Events, are supported in full version.

Hello,

This is not working. I want to add a column for Serial Number that having incremented value.
How to do that . Please help.

Abu Ghufran answered 7 years ago

You can set incremented serial no, using on_insert event.
In on_insert callback function, you can run a select query to fetch max serial number and set it incremented for insert.
