Remove jqGrid editoptions from a Column

Question

In my jqGrid, the onSelect function I set dataEvent on a particular column if the column cell is not an empty string.

As long as I edit a row where the particular cell has a value the dataEvent does not get set on the column. This is desired behavior.

Again if I edit a row where the cell is blank and the dataEvent is bound to the column. Again this is desired behavior.

However, once the second senerio is performed the dataevent seems locked to the column even when the check cell has a value.

My onSelect code:

function oSelect(id){
var vjobno = "";
vjobno = $("#timesheetlineitemsqueue").getRowData(id)['jobno'];
$("#timesheetlineitemsqueue").setColProp('date', { editoptions: {    dataUrl: '/TimeSheetWebApp/TimeSheetControllerServlet?lifecycle=weekdayoptions'}});
        $("#timesheetlineitemsqueue").setColProp('deptno', { editoptions: { dataUrl: '/TimeSheetWebApp/TimeSheetControllerServlet?lifecycle=departmentoptions'}});              
        $("#timesheetlineitemsqueue").setColProp('iphase', { editoptions: { dataUrl: '/TimeSheetWebApp/TimeSheetControllerServlet?lifecycle=phaseoptions'}});
        $("#timesheetlineitemsqueue").setColProp('icategory', { editoptions: { dataUrl: '/TimeSheetWebApp/TimeSheetControllerServlet?lifecycle=categoryoptions'}});
        if(vjobno == ""){
            $("#timesheetlineitemsqueue").setColProp('jobno', { editoptions: {dataEvents: [{ type: 'click', fn: function(e) {resetvalidation(this.name);  }},{ type: 'focus', fn: function(e) {resetvalidation(this.name);  }},{ type: 'change', fn: function(e) {validatejobnumber(this.value);  }},]}});
        }           
    };

It's important to understand that getGridParam returns the reference to internal parameters used by jqGrid. Thus you can use for example

var p = $("#timesheetlineitemsqueue").jqGrid("getGridParam");

and access to colModel using p.colModel . Alternatively you can use

var colModel = $("#timesheetlineitemsqueue").jqGrid("getGridParam", "colModel");

to get the reference to colModel array.

To get the column item, which have the name jobno , one can use iColByName in free jqGrid . Then

var cm = p.colModel[p.iColByName.jobno];

If you use some old version of jqGrid instead of free jqGRid then you can find the index of jobno in the loop (see the code of getColumnIndexByName in the answer for example).

Now you can set any property of cm item without usage setColProp . In the same way you can use delete to delete the property. For example

delete cm.editoptions.dataEvents;
