You can create GridView with appropriate columns dynamically using converter. Here is working example:

MainWindow.xaml

MainWindow.xaml.cs

using System.Collections.Generic;
using System.Windows;

namespace WpfApplication1
{
    /// 

    /// Interaction logic for MainWindow.xaml
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            DataContext = new ViewModel();
        }
    }

    public class ViewModel
    {
        public ColumnConfig ColumnConfig { get; set; }
        public IEnumerable Products { get; set; }

        public ViewModel()
        {
            Products = new List { new Product { Name = "Some product", Attributes = "Very cool product" }, new Product { Name = "Other product", Attributes = "Not so cool one" } };
            ColumnConfig = new ColumnConfig { Columns = new List { new Column { Header = "Name", DataField = "Name" }, new Column { Header = "Attributes", DataField = "Attributes" } } };
        }
    }

    public class ColumnConfig
    {
        public IEnumerable Columns { get; set; }
    }

    public class Column
    {
        public string Header { get; set; }
        public string DataField { get; set; }
    }

    public class Product
    {
        public string Name { get; set; }
        public string Attributes { get; set; }
    }
}

ConfigToDynamicGridViewConverter.cs

using System;
using System.Globalization;
using System.Windows.Controls;
using System.Windows.Data;

namespace WpfApplication1
{
    public class ConfigToDynamicGridViewConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var config = value as ColumnConfig;
            if (config != null)
            {
                var grdiView = new GridView();
                foreach (var column in config.Columns)
                {
                    var binding = new Binding(column.DataField);
                    grdiView.Columns.Add(new GridViewColumn {Header = column.Header, DisplayMemberBinding = binding});
                }
                return grdiView;
            }
            return Binding.DoNothing;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotSupportedException();
        }
    }
}
