这是我的代码,位于.ascx
页面上:
<% for (int i = 1; i <= 10; i++)
{ %>
<asp:TextBox ID="myTextBox_<%=i %>" runat="server" Width="100%" CssClass="focus_out reset_content"></asp:TextBox>
<% } %>
但我得myTextBox_<%=i %>
不是有效的识别者。那么,我该如何设置“动态ID”?

您需要为文本框创建一个容器,例如Panel控件,然后使用后面代码中的Page_Load循环并将文本框添加到面板。
示例:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Panel ID="pnlContainer" runat="server" />
</div>
</form>
</body>
</html>
代码背后:
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
for (int i = 1; i <= 10; i++) {
TextBox txtNewTextBox = new TextBox();
txtNewTextBox.ID = "myTextBox_" + i;
pnlContainer.Controls.Add(txtNewTextBox);
}
}
}
