c#动态循环TextBox问题，望高手之路!!
前台主要实现程序：

C# code

        <asp:Panel ID="Panel1" runat="server" Width="105px">        </asp:Panel>              <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>        <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>        <asp:Label ID="Label3" runat="server" Text="Label"></asp:Label>

后台代码：

C# code

        string a = ",序号,车号,姓名,联系方式";        string[] s = a.Split(new string[1] { "," }, System.StringSplitOptions.None);        for (int i = 1; i <= 3; i++)        {            TextBox txt = new TextBox();            txt.ID = "TextBox" + i.ToString();            //txt.top = i * 20;            Panel1.Controls.Add(txt);            ((Label)this.FindControl("label" + i)).Text = s[i];        }

我现在想问的是，如何自动生成前台的label，并且加在TextBox 的前面？然后在每个TextBox后面加个换行，最终显示方式如下：

C# code

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><input name="TextBox1" type="text" id="TextBox1" /><br><asp:Label ID="Label2" runat="server" Text="Label"></asp:Label><input name="TextBox2" type="text" id="TextBox1" /><br><asp:Label ID="Label3" runat="server" Text="Label"></asp:Label><input name="TextBox3" type="text" id="TextBox1" /><br>

希望高手指点哈！100分就这点了！
还有就是有没有更好的实现方式呀？小弟不胜感谢！

[解决办法]

C# code

        string a = ",序号,车号,姓名,联系方式";        string[] s = a.Split(new string[1] { "," }, System.StringSplitOptions.None);        for (int i = 1; i <= 3; i++)        {            Label lb = new Label();            lb.ID = "Label" + i.ToString();            TextBox txt = new TextBox();            txt.ID = "TextBox" + i.ToString();            lb.Text = "<br />"+s[i];            Panel1.Controls.Add(lb);            Panel1.Controls.Add(txt);        }
[解决办法]
通过后台编程的方式可以直接实现。
以下为前台

C# code<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
[解决办法]
另外，不建议使用后台编程方式实现，除非前台结构不确定。

怎么感觉拉的比你生产的快吧。。
要不做个表把TextBox放repeater里面绑定上。。。
[解决办法]
string a = ",序号,车号,姓名,联系方式";  
string[] s = a.Split(new string[1] { "," }, System.StringSplitOptions.None);  
for (int i = 1; i <= 3; i++) {  
 TextBox txt = new TextBox();  
 txt.ID = "TextBox" + i.ToString(); //txt.top = i * 20;  
 Label la = new Label();  
 la.Text = s[i];
 Panel1.Controls.Add(la);
 Panel1.Controls.Add(txt);
 Panel1.Controls.Add(new HtmlGenericControl("br"));   
}

[解决办法]
完全按照
<asp:Panel ID="Panel1" runat="server" Width="105px">
 </asp:Panel>
 <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
这样的代码结构的做法
