You can use editRow
option in loop in the loadComplete
like,
$("#jQGrid").jqGrid({
url: '../Controller/Action',
datatype: "json",
colNames: [...],
colModel: [...],
.
.
.
gridview: true,
loadonce: true,
loadComplete: function () {
//just make all the row to editmode
ids = $("#jQGrid").jqGrid('getDataIDs');
var l = ids.length;
for (var i = 0; i < l; i++) {
$("#jQGrid").jqGrid('editRow', ids[i], true);
}
},
rowNum: 10
});
