  <pre><code>             $('#gerList').jqGrid({
              ajaxGridOptions: {

                      $('#gerList')[0].grid.hDiv.loading = false;
                      alert('An error has occurred.');

                          return '&lt;input type="text" style="width: 40px" name="txtMin" id="txt_' + option.rowId + '" value="' + cellValue + '" /&gt;';
                      }
                  },

                  console.log("final");
                  var $txt = $(e.target).closest('tr').find('input[type="text"]');
                  alert($txt);
                   $txt.attr('value', rowid);
                   return true; // allow row selection*/
                  return true;
              },
              sortorder: 'desc'
          }).navGrid('#gerListPager', { edit: false, add: false, del: false, search: false, refresh: false });
  </code></pre>
  
  <p>Please suggest me what is wrong to use this textbox in jqgrid.</p>
  
  <p>In grid UI, all fields are non editable except textbox field appear to allow edit always.</p>
  
  <p>Thanks</p>
