动态生成的table中需要给对应行的label赋值，高手请进来看看！
for (int i = 0; i < nums; i++)
  {
  tr = new TableRow();
  for (int j = 0; j < 1; j++)
  {
  tc = new TableCell();
  tc.Text = dst.Tables[0].Rows[i][j].ToString();
  tr.Cells.Add(tc);
  }
  tc = new TableCell();
  LinkButton lkbtn = new LinkButton();

  lkbtn.ID = tp + Convert.ToString(i);
  lkbtn.Text = "记录时间";
  lkbtn.Click += new EventHandler(lkbtn_Click);
   
  tc.Controls.Add(lkbtn);
  tr.Cells.Add(tc);
   
  tc = new TableCell();
  lbltxt = new Label();
  lbltxt.Text = " ";
   
  tc.Controls.Add(lbltxt);
  tr.Cells.Add(tc);

  tb.Rows.Add(tr);
  }
  dst.Dispose();
  }

  protected void lkbtn_Click(object sender, EventArgs e)
  {
  LinkButton btn = sender as LinkButton;
  
  btn.Text = "∨";
   
  lbltxt.Text = DateTime.Now.ToString();


注：以上为代码，已经实现了，点击“lkbtn_click"后，对应行的text变为∨，但lbltxt.text的值始终不能给对应行赋值，而是给最后一后的那一列“时间”赋值，不知道如何改，请求高人指点，这里多谢了！！
效果如下图



------解决方案--------------------
protected void lkbtn_Click(object sender, EventArgs e)
{
LinkButton btn = sender as LinkButton;
btn.Text = "∨";
TableCell c = (btn.Parent.Parent as TableRow).Cells[2];
Label x = c.Controls[0] as Label;
x.Text = DateTime.Now.ToString();
}
