Question

I am using jqGrid 4.0.0, beforeProcessing never gets fired for each postBack, it has not been triggered at all, please assist!

$('#jqgInventory').jqGrid({
    autowidth: true,
    caption: 'Inventory',
    datatype:'json',
    forceFit: true,
    gridview: true,
    height: 500,
    hidegrid: false,
    ignoreCase: true,
    loadui: 'disable',
    pager:'#pager',
    mtype: 'post',
    rowNum:25,
    shrinkToFit: true,
    url:'/MCI/Inventory/Inventory/GetIndexGridData',
    viewrecords: true,
    postData: { modelView: JSON.stringify(model), __RequestVerificationToken:   $('[name="__RequestVerificationToken"]').val() },
    beforeProcessing:  function(data, status,xhr){beforeProcessing(data,status,xhr)},
    beforeRequest: function() {$('#gridScript').block();},
    beforeSelectRow: function(rowid, e) {return false;},
    gridComplete: function() {$('#lblVehicleCount').html($('#jqgInventory').getGridParam('records'));$('#gridScript').unblock();Inventory.modifyGridCellClick();},
    loadComplete: function(xhr) {GetGridData(xhr);},

If you want to use new features of jqGrid you should use the last version of jqGrid. You can download it from here.

The callback function beforeProcessing will be not called in jqGrid 4.0.0 because it was introduced in the version 4.2.0.
