and here is the page (Coffee.aspx.cs) code
using System;
using System.Collections;
using System.Text;
namespace Pages
public partial class Pages_Coffee : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
FillPage();
private void FillPage()
ArrayList coffeeList = ConnectionClass.GetCoffeeByType(DropDownList1.SelectedValue);
StringBuilder sb = new StringBuilder();
foreach (Coffee coffee in coffeeList)
sb.Append(
string.Format(
@"<table class='coffeeTable'>
<tr>
<th rowspan='6' width='150px'><img runat='server' src='{6}' /></th>
<th width='50px'>Name: </td>
<td>{0}</td>
</tr>
<tr>
<th>Type: </th>
<td>{1}</td>
</tr>
<tr>
<th>Price: </th>
<td>{2} $</td>
</tr>
<tr>
<th>Roast: </th>
<td>{3}</td>
</tr>
<tr>
<th>Origin: </th>
<td>{4}</td>
</tr>
<tr>
<td colspan='2'>{5}</td>
</tr>
</table>", coffee.Name, coffee.Type, coffee.Price, coffee.Roast, coffee.Country, coffee.Review, coffee.Image));
lblOuput.Text = sb.ToString();
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
FillPage();
also tis is the page (Coffee.aspx)code
<%@ Page Title="" Language="C#" MasterPageFile="~/Masterpage.master" AutoEventWireup="true" CodeFile="Coffee.aspx.cs" Inherits="Coffee" %>
<script runat="server">

</script>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<p>
Select a type:<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="sds_type" DataTextField="type" DataValueField="type" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
</asp:DropDownList>
<asp:SqlDataSource ID="sds_type" runat="server" ConnectionString="<%$ ConnectionStrings:CoffeeDBConnectionString %>" SelectCommand="SELECT DISTINCT [type] FROM [coffee] ORDER BY [type]"></asp:SqlDataSource>
</p>
<p>
<asp:Label ID="lblOutput" runat="server" Text="Label"></asp:Label>
</p>
</asp:Content>
this is th (ConnectionClass.cs)code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Collections;
using System.Configuration;
using System.Data.SqlClient;
public static class ConnectionClass
private static SqlConnection conn;
private static SqlCommand command;
static ConnectionClass()
string connectionString =
ConfigurationManager.ConnectionStrings["coffeeConnection"].ToString();
conn = new SqlConnection(connectionString);
command = new SqlCommand("", conn);
public static ArrayList GetCoffeeByType(string coffeeType)
ArrayList list = new ArrayList();
string query = string.Format("SELECT * FROM coffee WHERE type LIKE '{0}'", coffeeType);
try
conn.Open();
command.CommandText = query;
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
int id = reader.GetInt32(0);
string name = reader.GetString(1);
string type = reader.GetString(2);
double price = reader.GetDouble(3);
string roast = reader.GetString(4);
string country = reader.GetString(5);
string image = reader.GetString(6);
string review = reader.GetString(7);
Coffee coffee = new Coffee(id, name, type, price, roast, country, image, review);
list.Add(coffee);
finally
conn.Close();
return list;
(web.confg)code
<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings>
<clear/>
<add name="coffeeConnection"
connectionString="Data Source=LOCALHOST\SQLEXPRESS;Initial Catalog=CoffeeDB;Integrated Security=True"
providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<compilation debug="true" targetFramework="4.0">

</assemblies>
</compilation>

</system.web>
</configuration>
and finally this is the SQL code
GO

SET IDENTITY_INSERT [dbo].[coffee] OFF
I am still a beginner ~~ I need to understand what are these errors and how to solve them

Answer 1

Hello,
Welcome to MSDN forum.
I am afraid that the issue is out of support range of VS General Question forum which mainly discusses
the usage of Visual Studio IDE such as WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Because your issue is about website, I suggest that you can consult your issue on ASP.NET forum:
http://forums.asp.net/
 for better solution and support.
Best regards,
