using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
TextBox t = new TextBox();
t.ID = "a";
this.Label1.Controls.Add(t);
}
}
为什么会将我Label1的值覆盖了，怎么能不覆盖Label1并且能在Label1下面 求大家帮忙

把你的刷新按钮放在UpdatePannel中，不去刷新TextBox所在的区域就可以了！

下面是动态添加行的代码（行中包括textbox），你稍微改改就就ok了
- C# code
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><html><head><script type="text/javascript">function contactlist(){ var table = document.getElementById("contactTable"); var tr = table.insertRow(table.rows.length);//添加一行 tr.align="center"; tr.bgcolor="#F3F4F3"; tr.height="23"; //添加五列 var td0 = tr.insertCell(0); td0.width="20%"; var td1 = tr.insertCell(1); td1.width="20%"; var td2 = tr.insertCell(2); td2.width="8%"; var td3 = tr.insertCell(3); td3.width="30%"; var td4 = tr.insertCell(4); td4.width="20%"; //设置列内容 td0.innerHTML = ""; td1.innerHTML = "<input type='file' id='dataAudio' name='dataAudio'/><input type='hidden' name='dataAudios'/><input type='hidden' name='audioOldName'/>"; td2.innerHTML = "<input type='text' name='playDateTime' id='playDateTime' onkeyup='validateNumber(this);' size='5' maxlength='3' style='color: red' />"; td3.innerHTML = "<input type='text' name='content' id='content' size='35' maxlength='300'/>"; td4.innerHTML = "<input type='button' value='删除' onclick='removeRow(this.parentNode.parentNode)'/>"; }function removeRow(r){ var root = r.parentNode; var allRows = root.getElementsByTagName('tr'); if(allRows.length > 3){ root.removeChild(r); }else{ alert("不能删除改行！"); }}</script ></head><body><table id="contactTable" width="98%" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#D9D9D9"> <tr bgcolor="#F3F4F3" align="center" height="23"> <td colspan="5" align="left"><input type="button" value="添加帧" class="button" onclick="return contactlist();"/></td> </tr> <tr bgcolor="#F3F4F3" align="center" height="23"> <td width="20%">上传图片</td> <td width="20%">上传声音</td> <td width="8%">播放时间</td> <td width="30%">内 容</td> <td width="20%">操作</td> </tr> </table></body></html>
