title: Prevent jqGrid from entering edit cell using beforeCellEdit event?
body: <p>Is it possible to somehow stop the cell from entering edit mode, when catching the event beforeCellEdit?</p>
  
  <pre><code>beforeEditCell: function (rowid, cellname, value, irow, icol) {
      if (cellname != 'aSpecificCol')
          return;
  
      var grid = $("#grid");
  
      if (aCondition == "something")
          grid.setColProp('aSpecificCol', { editable: false });
      else
          grid.setColProp('aSpecificCol', { editable: true });
   }
  </code></pre>
  
  <p>The event fires, but the setting of column property seems to not changing the edit mode.</p>
