Try adding these lines.

Get parent selected row, reload, make parent row selection.

var selr = jQuery('#list1').jqGrid('getGridParam','selrow');
jQuery('#list1').trigger('reloadGrid',[{current:true}]);
jQuery('#list1').jqGrid('setSelection',selr,true);
return [true, ''];

Hi!

It doesn't works. The result is the same. It reloads parent grid, parent row is selected but add/edit/delete buttons in detail grid are inaccessible.

In detail grid events (Invoice detail):

$e["on_insert"] = array("add_det_invoice", null, true);
$e["on_after_insert"] = array("fnRefreshTotalValuesInvoice",null, false);
$e["on_after_update"] = array("fnRefreshTotalValuesInvoice",null, false);
$e["on_after_delete"] = array("fnRefreshTotalValuesInvoice",null, false);
$detailgrid->set_events($e);

function add_det_invoice(&$data)
{
$id = intval($_GET["rowid"]);
$data["params"]["idinvoice"] = $id;
}

function fnActualizaVenta(&$data)
{
$id = intval($_GET["rowid"]);
//[..]
// mysql_query updating total values in Invoice
//[..]
}

In detail grid options:

$detailopt["add_options"]["afterSubmit"] = "function(){var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{current:true}]); jQuery('#list1').jqGrid('setSelection',selr,true); return [true, ''];}";
$detailopt["edit_options"]["afterSubmit"] = "function(){var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{current:true}]); jQuery('#list1').jqGrid('setSelection',selr,true); return [true, ''];}";
$detailopt["delete_options"]["afterSubmit"] = "function(){var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{current:true}]); jQuery('#list1').jqGrid('setSelection',selr,true); return [true, ''];}";
$detailgrid->set_options($detailopt);

Rectify:

function fnRefreshTotalValuesInvoice(&$data)
{
$id = intval($_GET["rowid"]);
//[..]
// mysql_query updating total values in Invoice
//[..]
}

If you are using subgrid, you can simple enable auto-expand last opened subgrid on refresh.

add persist settings include files and jscode

And in detail code, connect aftersave and aftersubmit events to reload parent.

// reload parent on update
$grid["onAfterSave"] = "function(){ jQuery('#list1').trigger('reloadGrid',[{jqgrid_page:1}]); }";
// reload parent on add
$grid["add_options"]["afterSubmit"] = "function(){jQuery('#list1').trigger('reloadGrid',[{jqgrid_page:1}]); return [true, ''];}";

Complete code here … you can replace in demos/master-detail folder and check.

I have a master detail grid.
Master grid –> Invoice header data (date, client, total values)
Detail Grid –> Invoice lines (description, quantity, price, tax….)

Put the last selection call in setTimeout function. All rest seems fine.

// reload master after detail update
$opt["onAfterSave"] = "function(){ var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{jqgrid_page:1}]); setTimeout( function(){jQuery('#list1').setSelection(selr,true);},500 ); }";

Hi, Abu!

I'm doing something wrong….

Screen capt:

Code:

Abu, in your code, when a detail line in grid is modified or added, if you select another line (in master or detail) and edit or adds a new one, edit form shows the data of the line edited/added before.

I have it!

In detail grid options:

$detailopt["add_options"]["afterSubmit"] = "function(){ var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{jqgrid_page:1}]); setTimeout( function(){jQuery('#list1').setSelection(selr,true);},500 ); return [true, ''];}";
$detailopt["edit_options"]["afterSubmit"] = "function(){ var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{jqgrid_page:1}]); setTimeout( function(){jQuery('#list1').setSelection(selr,true);},500 ); return [true, ''];}";
$detailopt["delete_options"]["afterSubmit"] = "function(){ var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{jqgrid_page:1}]); setTimeout( function(){jQuery('#list1').setSelection(selr,true);},500 ); return [true, ''];}";

//$detailopt["onAfterSave"] = "function(){ var selr = jQuery('#list1').jqGrid('getGridParam','selrow'); jQuery('#list1').trigger('reloadGrid',[{jqgrid_page:1}]); setTimeout( function(){jQuery('#list1').setSelection(selr,true);},500 ); }";
$detailgrid->set_options($detailopt);

If you are using dialog based editing, afterSubmit event will work.
In case of inline editing, onAfterSave will be required.

Glad to know it's resolved.
