ASP控件不起作用
[英]Asp Controls not working
問題描述
我正准備使用Telerik列表視圖。 我剛剛添加了一個SqlDataSource，我想在服務器端提供select命令。 但是，當我想在.cs文件中訪問它時，即使未顯示任何控件，也無法訪問SqlDataSource1。 當我嘗試使用Label1.Text而不是.cs文件中的label1時，我添加了標簽。

這是我的aspx.cs類
using System;
using System.Collections.Generic;
using System.Collections;
using System.Configuration;
using System.Web.Security;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls.WebParts;
using System.Data;
using System.Xml.Linq;
using System.Data.SqlClient;
namespace NoidaPortal
{
public partial class category : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack == false)
{
string s = Request.QueryString["cat"];
string s1 = Request.QueryString["sub"];
**I Just want to give here a SqlDataSource.Select command**
}
}
}
3 個解決方案

之所以可能，是因為您沒有提到頁面的背后代碼。 將此作為第一行添加到您的aspx頁面
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="yourfile.aspx.cs" Inherits="YourProjectName.YourASPXPageName" %>

您的內容占位符中包含某些內容，因為您使用的是母版。 您無法在控件上獲得智能感知的原因是因為頁面不合規。
刪除這些標簽：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<body>
<form id="form1" runat="server">
然后嘗試編譯您的應用程序。 修復編譯器拋出的所有錯誤並重新編譯。 一旦應用程序可編譯，您的智能就應該重新開始工作。

是的，我在這里找到了解決方案...我必須通過右鍵單擊ProjectFolder並單擊“轉換為Web應用程序”將其轉換為webApplication。 比起智能感知開始工作了。
