Шаг 1. Создаем новый проект
Шаг 2. Добавим DataGrid в xaml файл
  Файл MainWindow.xaml
<Window x:Class="WpfDataGrid.MainWindow"
          xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
          xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
          xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
          xmlns:local="clr-namespace:WpfDataGrid"
          mc:Ignorable="d"
          Title="MainWindow" Height="450" Width="800">
     <Grid>

          <DataGrid AutoGenerateColumns="False"
                         Margin="10"
                         IsReadOnly="True"
                         ItemsSource="{Binding MyData}"
                         FontFamily="Gisha" FontSize="20">

               <DataGrid.Columns>

                    <!-- text column -->
                    <DataGridTextColumn Header="Customer" Binding="{Binding Customer}" Width="150" />

                    <!-- text column -->
                    <DataGridTextColumn Header="Item" Binding="{Binding Item}" Width="150"/>

                    <!-- text column with vertical alignment=center -->
                    <DataGridTemplateColumn Header="Price" Width="120">
                         <!-- center data -->
                         <DataGridTemplateColumn.CellTemplate>
                              <DataTemplate>
                                   <TextBlock Text="{Binding Price}" VerticalAlignment="Center" HorizontalAlignment="Center"/>
                              </DataTemplate>
                         </DataGridTemplateColumn.CellTemplate>
                         <!-- center header -->
                         <DataGridTemplateColumn.HeaderStyle>
                              <Style TargetType="{x:Type DataGridColumnHeader}">
                                   <Setter Property="HorizontalAlignment" Value="Center"/>
                                   <Setter Property="Background" Value="Transparent"/>
                              </Style>
                         </DataGridTemplateColumn.HeaderStyle>
                    </DataGridTemplateColumn>

                    <!-- button -->
                    <DataGridTemplateColumn>
                         <DataGridTemplateColumn.CellTemplate>
                              <DataTemplate>
                                   <Button Command="{Binding ClickMyButton1, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"
                                                  CommandParameter="{Binding}"
                                                  Height="50"
                                                  Content="My button" />
                              </DataTemplate>
                         </DataGridTemplateColumn.CellTemplate>
                    </DataGridTemplateColumn>

               </DataGrid.Columns>

          </DataGrid>

     </Grid>
</Window>
Шаг 3. Добавим код в MainWindow.xaml.cs файл
  C#     Файл MainWindow.xaml.cs
using System;
using System.Collections.ObjectModel;
using System.Windows;
using System.Windows.Input;

namespace WpfDataGrid
{
     public class MyShop
     {
          public string Customer { get; set; }
          public string Item { get; set; }
          public string Price { get; set; }
     }

     class ButtonCommand : ICommand
     {
          public event EventHandler CanExecuteChanged;
          private Action<object> _callback;

          public ButtonCommand(Action<object> callback)
          {
               _callback = callback;
          }

          public virtual void Execute(object parameter) { _callback(parameter); }
          public virtual bool CanExecute(object parameter) { return true; }
     }

     public partial class MainWindow : Window
     {
          public ObservableCollection<MyShop> MyData { get; set; }
          public ICommand ClickMyButton1 { get; set; }

          public MainWindow()
          {
               InitializeComponent();

               // for binding
               this.DataContext = this;

               // data for grid
               MyData = new ObservableCollection<MyShop>()
               {
                         new MyShop() {Customer="ACME", Item="Widget", Price="100"},
                         new MyShop() {Customer="ACME", Item="Widget", Price="100"},
                         new MyShop() {Customer="ACME", Item="Tyre", Price="200"},
                         new MyShop() {Customer="Amazon", Item="Pen", Price="50"},
                         new MyShop() {Customer="Amazon", Item="Paper", Price="20"},
                         new MyShop() {Customer="Autodesk", Item="CAD", Price="10"},
                         new MyShop() {Customer="Autodesk", Item="File", Price="40"},
                         new MyShop() {Customer="ABC", Item="Flowers", Price="503"},
                         new MyShop() {Customer="ABC", Item="Sand", Price="706"}
               };

               ClickMyButton1 = new ButtonCommand((parameter => {
                    MyShop myShop = parameter as MyShop;
               }));
          }

     }
}
Шаг 4. Запускаем (Ctrl-F5 или Run)
На заметку! Как сделать scrolling для DataGrid
Если DataGrid находится внутри Grid то будет Scrolling

Пример:
<Grid>
     <DataGrid>
          ...
     </DataGrid>
</Grid>
или
<ScrollViewer>
     <DataGrid>
          ...
     </DataGrid>
</ScrollViewer>


Если DataGrid находится внутри StackPanel то НЕ БУДЕТ Scrolling

Пример:
<StackPanel>
     <DataGrid>
          ...
     </DataGrid>
</StackPanel>
