如何在asp.net中将CSS赋予工具提示？

Question

    protected void grd_RowDataBound(object sender, GridViewRowEventArgs e)
           {
               if (e.Row.RowType == DataControlRowType.DataRow)
               {
                   foreach (TableCell cell in e.Row.Cells)
                   {
                       string cellText = e.Row.Cells[5].Text;

                       if (cell.Text.Length > 10)
                       {
                           cell.Text = cell.Text.Substring(0, 10) + "....";
                           cell.ToolTip = cellText;
                       }
                   }
               }
           }

From the above method we have tooltip on every columns in the table. Below code shows that 6th column will only populate tooltip.

    <script type="text/javascript">
          $(document).ready(function() {
           focus.($("#grdStudentList td:nth-child(6)"));
          }); 
     </script>

How i will give css to this focus which display as tooltip.

请检查所有单词是否包含超过10个字符

( if (cell.Text.Length > 10)
