ondblClickRow: function(rowid) {

$(this).jqGrid('editGridRow', rowid, {height:275,reloadAfterSubmit:false,closeAfterEdit:true,closeOnEscape:true});

}

Now the dialog closes as expected. Hope this helps someone else...

What am I missing? I am using the following declaration for my grid.

$("#navgrid").jqGrid({

url:appendSession("/async/groups.html?x=1"),

datatype: "json",

hidegrid: false,

colNames:["Group ID","Group Name","Users in Group","Group Notes"],

colModel:[

{name:'id', index:'groupid', width:55, editable:false, editoptions:{readonly:true,size:10}, hidden:true},

{name:'groupname', index:'groupname', width:250, editable:true, editoptions:{size:25}, editrules:{required:true}, resizable:true},

{name:'users', index:'users', width:550, editable:true, edittype:"select", editoptions:{ multiple:true, size:3,

value: $.parseJSON( $.ajax({ url: appendSession('/async/users.html'), type:'post', data: { x:3 }, dataType: 'json', async: false, success: function(data, result) { if (!result) alert('Failure to retrieve the users.'); } }).responseText)

},

sortable:false, resizable:true},

{name:'groupnotes', index:'groupnotes', width:50, editable:true, edittype:"textarea", editrules:{edithidden:true}, editoptions:{rows:"5",cols:"30"}, hidden:true, sortable:false}

],

rowNum:10,

rowList:[10,20,30],

pager: '#pagernav',

sortname: "groupid",

viewrecords: true,

sortorder: "asc",

caption:"Groups Management",

editurl:appendSession("/async/groups.html?x=2"),

height:210,

ondblClickRow: function(rowid) {

$(this).jqGrid('editGridRow', rowid);

}

});

$("#navgrid").jqGrid('navGrid','#pagernav',

{}, //options

{height:275,reloadAfterSubmit:false,closeAfterEdit:true,closeOnEscape:true}, // edit options

{height:275,reloadAfterSubmit:false,closeAfterAdd:true,closeOnEscape:true, afterSubmit: function(response,postdata) { return [true,"",response.responseText]; } }, // add options

{reloadAfterSubmit:false,closeOnEscape:true}, // del options

{closeOnEscape:true,closeAfterSearch:true} // search options

);
