hi Abu
sorry to say, but I still have some trouble with this grid. I found that is has to do with the version of IE.

Google Chrome is ok (Versjon 33.0.1750.154 m)
IE10 is ok
IE10 is not ok if I run in compatible mode. All my users are running IE10 in compatible mode, so this is a problem for me.

It is a bit complicated. But I'll try to explain (all in IE10 compat mode)
If I set inlineadd=>true the page is not loading.
If I set inlineadd=>false the page is loading ok.
With inlineadd=>false after loading, the dropdown is cleared for old values when I edit a record. But only if the fields I want to display consist of two fields (concat).

Here is some of the code I use. As you know, I am using MS SQL server.
(I can post you the entire code if you like, it was too big for this forum).

Can you help me?

// —

$g->set_actions(array(
"add"=>true, // allow/disallow add
"inlineadd"=>false,
"clone"=>true, // allow/disallow clone
"edit"=>true, // allow/disallow edit
"delete"=>true, // allow/disallow delete
"view"=>true, // allow/disallow delete
"rowactions"=>true, // show/hide row wise edit/del/save option
"export_excel"=>true, // show/hide export to excel option – must set export xlsx params
"export_pdf"=>true, // show/hide export to pdf option – must set pdf params
"autofilter" => true, // show/hide autofilter for search
"search" => false // show single/multi field search condition (e.g. simple or advance)
)
);

$col["isnull"] = true; // THIS DOES NOT WORK, SO I HAVE TO USE SELECT..UNION!
//$str = $g->get_dropdown_values("select distinct id as k, (struktur+forretningNavn) as v from [INDIT].[dbo].[forretning] order by 2");
