如何分页……偶也想问

再帮楼主问一个:
新闻列中如
asdfsadfffffff.... 
如何使当鼠标置于新闻列上方,显示类似于tooltip的内容为新闻标题全称.此功能如何实现?

------解决方案--------------------
楼上的代码多了点!!!
一般情况下在dataview控件RowDataBound事件中写这么一段代码应该可以解决问题了
  string[] StrCol = new string[3];
       if ((e.Item.ItemType == ListItemType.Item) | (e.Item.ItemType == ListItemType.AlternatingItem))
       {

           string Title = "";
           Title = e.Item.Cells[1].Text;
           if (Title.Length > 10)//大于10个长度
           {
               e.Item.Cells[1].Text = "<a href=\"news_show.aspx?id=" + this.DGBulletin.DataKeys[e.Item.ItemIndex] + ">" + Title.Substring(1, 10) + "...</a>";
           }
           else
               e.Item.Cells[1].Text = "<a href=\"news_show.aspx?id=" + this.DGBulletin.DataKeys[e.Item.ItemIndex] + ">" + Title + "...</a>";
