i am a little confused about these features. With local data in "adjacency" mode sort does nothing, in "nested" sorts only roots items.

But when I use providing data by url sorting works great in nested. But when i want to searching it doesnt work.

I use this code for providing

if( (integer)$_REQUEST["nodeid"] >0) {
$n_lft = (integer)$_REQUEST["n_left"];
$n_rgt = (integer)$_REQUEST["n_right"];
$n_lvl = (integer)$_REQUEST["n_level"];

$n_lvl = $n_lvl+1;
$SQL = "SELECT account_id, name, acc_num, debit, credit, balance, level, lft, rgt FROM accounts WHERE lft > ".$n_lft." AND rgt < ".$n_rgt." AND level = ".$n_lvl." ORDER BY lft";
} else {
// initial grid
$SQL = "SELECT account_id, name, acc_num, debit, credit, balance, level, lft, rgt FROM accounts WHERE level=0 ORDER BY lft";
}

But search request don´t contain $_REQUEST["nodeid"]. So always i send the init grid.

Is here way to do searching on treegrid with providing data?

Here is my config:

var grid = $("#GroupHierarchyGrid");
grid.jqGrid({
url: '/_layouts/SPTools/GroupHierarchyGridProvider.aspx?Source=' + window.location.href,
treedatatype: "xml",
mtype: "POST",
colNames: ["id", "spid", "Title", "Members", "TaskListUrl", "Users"],
colModel: [
{ name: 'id', width: 25, align: "center", hidden: true, key: true },
{ name: 'spid', width: 25, align: "center", hidden: true },
{ name: 'name', search: true, stype: 'text' },
{ name: 'Members', align: "left", search: true, stype: 'text' },
{ name: 'TaskListUrl', align: "left", stype: 'text', search: true },
{ name: 'Users', align: "left", search: true, stype: 'text' }
],
treeGrid: true,
treeGridModel: 'nested',
ExpandColumn: 'name',
height: 'auto',
width: '800',
pager: "#ptreegrid",
caption: "Treegrid"
})

grid.jqGrid('filterToolbar', {
searchOnEnter: true
, stringResult: true
 , defaultSearch: 'cn'}
});

 Thank You very match
