<asp:datalist id="pt_zx" runat="server" Width="100%" Height="80px">
<ItemTemplate>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="5%"><img src="Images/dec.jpg" width="7" height="8">
</td>
<td width="95%"><a href='news/news.aspx?id=<%# DataBinder.Eval(Container.DataItem,"id").ToString() %>' target="_blank">
<%# CutString(DataBinder.Eval(Container.DataItem,"title").ToString(),12) %>
</a>
</td>
</tr>
</table>
</ItemTemplate>
</asp:datalist>

后台：
首先要引入Text命名空间
public static string CutString(string str, int len)
  {
   str = str.Trim();
   byte[] myByte = System.Text.Encoding.Default.GetBytes(str);
   if (myByte.Length > len)
   {
    string result = "";
    for (int i = 0; i < str.Length; i++)
    {
     byte[] tempByte = System.Text.Encoding.Default.GetBytes(result);
     if (tempByte.Length < len)
     {
      result += str.Substring(i, 1);
     }
     else
     {
      break;
     }
    }
    return result + "...";
   }
   else
   {
    return str;
   }
  }
