Question

I’m using jqGrid and I need to post a value from a cell that is not editable when I do inline editing.

I tried using:

 editData: {
   proiect: jQuery("#Id").getCell(jQuery("#Id").getGridParam('selrow'), 'ColName') 
}

I am not sure that I understand you correct. In any way editData is the property which can be used in case of form editing (see the documentation). If you need to send some additional information to the server extraparam or serializeRowData. The exact implementation depend on the way in which you use inline editing. For example if you call editRow directly inside of onSelectRow then you can do the following

onSelectRow: function (id) {
    var $this = $(this),
        cellValue = $this.jqGrid("getCell", id, 'ColName');

    if (id && id!==lastSel){ 
        $this.jqGrid("restoreRow", lastSel); 
        lastSel = id; 
    }

    $this.jqGrid("editRow", id, {
        keys: true,
        extraparam: {
            proiect: cellValue
        }
    });
}
