jQGrid - "reloadGrid" - Keep Position

Question

I'm trying to 'refresh' or 'reload' a grid and keep the row which has focus after the grid has been reloaded.

I've tried to do it as follows:-

var rowId = $("#dispatch").jqGrid('getGridParam','selrow');
var thisRow = (parseInt(rowId) + parseInt(1));  

$("#dispatch").trigger("reloadGrid");

setTimeout(function(){
    $("#dispatch").setSelection(thisRow);
}, 151);

But you can see it just from position #1 to the new position.

Is there any other way of reloading the grid and keeping focus position?

Tried:-

// Display Current Jobs

$('#btn-current').bind('click', function() {

    $.ajax({
        type: 'GET',
        url: 'scripts/php/jobs.controller.php',
        data: "id=" + "current",
        success: function(data){

             allButtons.removeClass('active');
             $('#btn-current').addClass('active');

             $("#dispatch").trigger("reloadGrid", [{current:true}]);

        }
    });

});

Grid:-

$(function () {

    var lastsel2
    var rowsToColor = [];

    $("#dispatch").jqGrid({

Answer 1

Instead of usage setSelection inside of setTimeout you need just use additional parameter of reloadGrid: current:true. See the answer for more details.

UPDATED: The code of gridComplete seems be the reason of your problem:

$("#dispatch").setSelection(0, true);   

it resets the selection of the grid after reloading to the row with the id="0".

I would strictly recommend you to replace the code of loadComplete to much more effective rowattr callback. See the answer for the corresponding code example.

Additionally you should not bind $('body').keyup on every row selection. In the way you bind (register) more and more new keyup event handles without unbinding the previous one. I'm not sure what you want to do in the part of the code, but you should probably move the code outside of onSelectRow callback.

I don't see any reason to set ondblClickRow with respect of setGridParam after the grid is created. Instead of that you can just include ondblClickRow callback directly in the list of jqGrid option during creating the grid (like you defined loadComplete, onSelectRow and gridComplete callbacks).

I recommend you to use $(this) instead of $('#dispatch') inside of any jqGrid callback.
