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
- HTML code
<%@ Page Language="C#" Debug="true" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> protected void Page_Load(object sender, EventArgs e) { 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.Text = s[i]; txt.ID = "TextBox" + i.ToString(); //txt.top = i * 20; Label la = ((Label)this.FindControl("label" + i)); la.Text = s[i]; Literal lt = new Literal(); lt.Text = "<br/>"; int il = GetControlIndex(la) + 1; form1.Controls.AddAt(il, lt); form1.Controls.AddAt(il, txt); } } private int GetControlIndex(Label l) { for (int i = 0; i < form1.Controls.Count; i++) { if (form1.Controls[i].ID == l.ID) return i; } return 0; }</script><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title></head><body> <form id="form1" runat="server"> <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> </form></body></html>
