  8. </head>  
  9. <body>  
  10.     <form id="form1" runat="server">  
  11.     <div>  
  12.      <asp:GridView ID="grvEmployee" runat="server">  
  13.         </asp:GridView>

  7. using System.Configuration;  
  8. using System.Data.SqlClient;  
  9. using System.Data;  
  10.   
  11. namespace EmployeeDemo  
  12. {  
  13.     public partial class Emploee : System.Web.UI.Page  
  14.     {  
  15.         protected void Page_Load(object sender, EventArgs e)  
  16.         {  
  17.             if (!this.IsPostBack)  
  18.             {  
  19.                 string connectionString = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;  
  20.                 string selectSQL = "SELECT * from Employee";  
  21.                 SqlConnection con = new SqlConnection(connectionString);  
  22.                 SqlCommand cmd = new SqlCommand(selectSQL, con);  
  23.                 SqlDataAdapter adapter = new SqlDataAdapter(cmd);  
  24.                 DataSet ds = new DataSet();  
  25.                 adapter.Fill(ds, "Employee");  
  26.   
  27.                 grvEmployee.DataSource = ds;  
  28.                 grvEmployee.DataBind();  
  29.             }  
  30.         }  
  31.     }  
  32. }  
Add connection string in web.config file as in the following code.

Web.config
  1. <connectionStrings>  
  2.    <add name="DefaultConnection" connectionString="Data Source=Mukesh-Pc;Initial Catalog=Test; User Id=sa; Password=adminadmin;" providerName="System.Data.SqlClient" />  
  3. </connectionStrings>
