How can we access database without using LINQ in mvc3 application in asp.net.
I have to bind a gridview.Now I have written the code in Controller like below:

public ActionResult Index()
{
string strcon = ConfigurationManager.ConnectionStrings["conStr"].ToString();
SqlConnection con = new SqlConnection(strcon);
con.Open();

SqlCommand cmd = new SqlCommand("SP_Dis", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);

return View(dt);
}
Is this Possible?

Now I have to bind the dt to a gridview.How can I do it?

Use enterprise library.

Download Enterprise Library from here[^]

Add something like this into your web.config

XML

<configSections>
  <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data" />
</configSections>
<dataConfiguration defaultDatabase="Connection String" />
<connectionStrings>
  
  <add name="yourDatabase" connectionString="Database=yourDatabase;Server=(local);Integrated Security=SSPI" providerName="System.Data.SqlClient" />
</connectionStrings>

Then access the databse using code like this:

C#

public static User LogOn(string userCode, string password)
        {
            Database db = DatabaseFactory.CreateDatabase("eValue8DB");
            DbCommand dbCommand = db.GetStoredProcCommand("Get_User");
            db.AddInParameter(dbCommand, "UserCode", System.Data.DbType.String, userCode);
            db.AddInParameter(dbCommand, "Password", System.Data.DbType.String, password);

            using (IDataReader reader = db.ExecuteReader(dbCommand))
            {
                if (reader.Read())
                {
                    // create and return the user object from the datareader
                }
                else
                {
                    return null;
                }
            }
        }

P.S. you need to add a reference to the entrprise library in the project in which yo uhave this DB access code
