jQuery Grid Plugin - jqGrid

Hi,

I use the cell editing (with jqGrid 3.5.2) and I need to disable or remove an input element (checkbox) depending on the context of each row.

I use the callback afterInsertRow() to do that:

    To disable the checkbox:
   
        $("#gridid  tr[id='"+rowid+"'] > td:eq(6) > input").attr("disabled",true);
       
    To remove the checkbox:
   
        $("#gridid  tr[id='"+rowid+"'] > td:eq(6)").html("");
       
The problem is that jqGrid is "too" smart because it restores the checkbox and activates it when I click on the row.

Is it possible to keep the input element in the state set by afterInsertRow with the API (without modifying the code in grid.celledit.js) ?

Thanks for your advice.
