This common function can be used to retrieve the datas from database using stored procedure to datatable

 public static DataTable ExecuteDataTable(string storedProcedureName,
                                         params SqlParameter[] arrParam)
        {
            DataTable dt = new DataTable();

            // Open the connection 
            using (SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["AppDB"].ConnectionString))
            {
                cnn.Open();

                // Define the command 
                using (SqlCommand cmd = new SqlCommand())
                {
                    cmd.Connection = cnn;
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.CommandText = storedProcedureName;

                    // Handle the parameters 
                    if (arrParam != null)
                    {
                        foreach (SqlParameter param in arrParam)
                            cmd.Parameters.Add(param);
                    }

                    // Define the data adapter and fill the dataset 
                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        da.Fill(dt);
                    }
                }
            }
            return dt;
        }
