Hi Peter,

     Yes, the code that you have provided is almost correct. But to set the auto value of column, we will need to use SetText instead of SetValue. And also, we do not need to get the selected object and so on, because on OnBeforeAdd event, it will pass the rowObject, so we can just use that particular object.  Here is the snippet to do so:

  function WebGrid1_OnBeforeAdd(controlId, tblName, rowObject)
        {
            var WebGrid1 = ISGetObject(controlId);
            var cells = rowObject.GetCells();
            var getCell = cells.GetNamedItem("Description");
            getCell.SetText("This is an auto fill", true)
                     
            return true;
        }

      I hope it helps and please, do not hesitate to ask if you have any other questions. Thank you.
