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



[解决办法]
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();
}
