Hello,

You can use the ClientSideEvents of UltraWebGrid and use events MouseOverHandler="Over" MouseOutHandler="Out" . With javascript function over and out you can manipulate background of rows:

<ClientSideEvents MouseOverHandler="Over" MouseOutHandler="Out"/>

...

<script type="text/javascript" language="javascript">   

    function Over(gridNane, cellID, objectType){       

        var cell = igtbl_getCellById(cellID);

        setRowBackColor(cell.Row, "red");        

    }

    function Out(gridNane, cellID, objectType){       

        var cell = igtbl_getCellById(cellID);

        setRowBackColor(cell.Row, "white");    

    }

    function setRowBackColor(row, color){

        var cells = row.getCellElements();       

        for (var i = 0; i < cells.length; i++) {

            cells[i].style.backgroundColor = color;       

        }  

    }

    </script>

...
