<%@ 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:GridView runat="server" ID="datagrid" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3"> <RowStyle ForeColor="#000066" /> <FooterStyle BackColor="White" ForeColor="#000066" /> <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" /> <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" /> <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> </asp:GridView> </div> </form> </body> </html>
Open your web.config file and add a ConnectionString for making connection to SQL database.
<connectionStrings> <add name="myconnectionString" connectionString="Data Source=h-pc;Initial Catalog=mydatabase;Persist Security Info=True;User ID=sa;Password=123" /> </connectionStrings>
Open the .cs page (code file) and edit it as following :
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;
using System.Data.SqlClient;
using System.Data.Sql;
public partial class _Default : System.Web.UI.Page
{
String myconnectionString = ConfigurationManager.ConnectionStrings["myconnectionstring"].ConnectionString;
SqlConnection con;
SqlDataAdapter adapter;
DataSet ds;
SqlCommand cmd;
protected void Page_Load(object sender, EventArgs e)
{
con = new SqlConnection(myconnectionString);
cmd = new SqlCommand("select * from mytable", con);
con.Open();
adapter = new SqlDataAdapter(cmd);
ds = new DataSet();
adapter.Fill(ds, "mytable");
datagrid.DataSource = ds.Tables[0];
datagrid.DataBind();
con.Close();
}
}
