the custom formatter function should be used to set contain of the cell and no attributes like the title attribute used for tooltips. The new 4.0 version of jqGrid support cellattr event which can be used to set cell attributes. See here, here (including demo examples) and here.

I would like to display different values in cell and tooltip (title).

For Eg.

I am trying to limit the number of characters displayed in the cell

and then display the actual value in the tooltip.

I used the formatter function but it seems that the tooltip value is directly picked from the cell value.

My code looks like this.

colModel:[  
               {name:'description',index:'description', width:100, sortable:false, align:'left',formatter:wrapFormatter}
  
               ],

function wrapFormatter (cellvalue, options, rowObject){    
    var titleVal = cellvalue;    
    if(cellvalue.length > 25) {        
        cellvalue = cellvalue.substring(0,25)+'...';        
    }
    $("#grid").setCell(options.rowId, cellvalue, '', '',{ title: titleVal});    
    return cellvalue;    
}

Any help would be appreciated

Thanks
