Adding column Dynamically

[bsolteam]

Hi,

Is there any demo or Api for adding column dynamically. Because i didn't find any thing for adding column dynamically. I need to add a column dynamically like, same way we are using in dynamic row adding.

Thanks in advance.

colModel is an array of columns.

Add the column to colModel the way you do array manipulation in javascript.

call refresh after it.

I am trying to add colums dynamically (I have some nested ones) and it doesn't seems to be working.
What I am doing wrong?
function addWklyOtWO() {
    var woItm = {title:"<b>2</b>", minWidth:50, dataIndx: "num2", resizable: false, align:"center",
          colModel:[
                   {title:"<b>WO#</b>", minWidth:100, dataIndx: "woNo2", resizable: false, align:"center", cls:'Start-DayBorder',hidden:true}, 
                   {title:"<b>Units</b>", minWidth:40, dataIndx: "unts2", resizable: false, align:"center",hidden:true},
                   {title:"<b>Task#</b>", minWidth:40, dataIndx: "tsk2", resizable: false, align:"center",hidden:true},
                   {title:"<b>Ord Hrs</b>", minWidth:40, dataIndx: "ord_hrs2", resizable: false, align:"center",hidden:true},
                   {title:"<b>Veh</b>", minWidth:40, dataIndx: "veh2", resizable: false, align:"center",hidden:true},
                   {title:"<b>Veh Hrs</b>", minWidth:40, dataIndx: "veh_hrs2", resizable: false, align:"center",hidden:true},
                   {title:"",dataIndx:"vcRecId2",hidden:true},
                   {title:"",dataIndx:"lcRecId2",hidden:true}
                 ]};

   var otColMdl = $("#grid_wkly_ot").pqGrid("option", "colModel"),
      woColMdl = otColMdl[0].colModel;
   
   woColMdl.push(woItm);
   
   $("#grid_wkly_ot").pqGrid("option", "colModel", otColMdl);   
   $("#grid_wkly_ot").pqGrid("refresh");
}

Put a breakpoint in the function and check the value of otColMdl before updating colModel.

I do see everything fine in both woColMdl and otColMdl.
Maybe the problem with the nested columns?

Got it work. It is related to the nested columns

I added one line after the push:
   woColMdl.push(woItm);
   otColMdl[0].colModel = woColMdl;

and everything is working.
Thanks a lot.
