Highlighting Gridview Row on Mouse Over event when Gridview ALTERNATE rows are applied in Asp.Net

Either we can write code on Gridview Rowcreated event or RowDataBound event.

protected void project_grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //Highlight Row on Mouse over event
        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#F0D8D8'");

        //On Mouse out event restore girdview row color based on alternate row color
        if (e.Row.RowIndex % 2 == 0) 
        {
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#F5F5DC'");
        }
        else
        {
           //Reset Row Color(White Color)
           e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
       }
   }
}
