vs2008 asp.net 的 DataGrid 问题：过宽加省略号

下面是我的一个页面的完整代码
问题：
当"标题"这列的内容太长时，如何截断并在尾部显示省略号，而不是扩宽表列<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TopicList.aspx.cs" Inherits="TestList" %>

  1.   

    在绑定事件里处理
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
      if (e.Row.RowType == DataControlRowType.DataRow)
      {
        if (e.Row.Cells[1].Text.Length > 10)
        {
          e.Row.Cells[1].Text = e.Row.Cells[1].Text.Substring(0, 10) + "...";
        }
      }
    }

    这里很多解决办法
      

  3.   

    不会吧，有空格？
    if (e.Row.Cells[1].Text.Trim().Length > 10)
      {
      e.Row.Cells[1].Text = e.Row.Cells[1].Text.Trim().Substring(0, 10) + "...";
      }
