我有这段代码，我想问一下如何将查询结果显示到名为“Textbox1”的文本框中
<%@ page language="C#" autoeventwireup="true" codeBehind="Default.aspx.cs" inherits="MainPage, App_Web_rlctbjj5" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
string connect = ConfigurationManager.ConnectionStrings["TDBSConnectionString"].ConnectionString;
string query = "SELECT news, news_date FROM [IBSI].[dbo].[ibsi.news]";
if (query != null)
{
using (SqlConnection conn = new SqlConnection(connect))
{
using (SqlCommand cmd = new SqlCommand(query, conn))
{
conn.Open();
SqlDataReader rdr = cmd.ExecuteReader();
if (rdr.HasRows)
{
while (rdr.Read())
{
Response.Write("<p>");
Response.Write("<strong>" + rdr["news"].ToString() + "</strong><br />");
Response.Write(rdr["news_date"].ToString() + "</p>");
}
}
}
}
}
else
{
Response.Write("<p>No customer selected</p>");
}
Response.End();
}

我用它来在屏幕上显示检索数据的值。
Response.Write("<p>");
Response.Write("<strong>" + rdr["news"].ToString() + "</strong><br />");
Response.Write(rdr["news_date"].ToString() + "</p>");
答案 0 :(得分：1)
通常你会写这样的东西：
TextBox1.Text = rdr["news"].ToString();
但是，您的查询可能会返回超过1行（并且超过1列）。 TextBox只能容纳1个值，所以如果你这样做，你只会看到最后一行的内容。
在你的情况下，最好使用一个可以显示多行值的控件，例如GridView，ListView，Repeater或者DataList
答案 1 :(得分：0)
它使用的是dojo框架。因此，请尝试在此处使用控件：http://dojotoolkit.org/。 对于dojo文本框，设置值为dijit.byId（'TextBox1'）。set（'value'，'sampleValue'）; 我从头开始创建该项目。但我想你是继续它的人。祝好运。 ：）
