Hi Jacob,

In the following MainWindow.xaml I name the Grid MainGrid to access it in the code behind:

<Window x:Class="WpfExperiments.MainWindow"
       
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
       
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
       
Title="MainWindow" Height="350"
Width="525">
    <Grid
Name="MainGrid"/>
</Window>

The DataItem class is not a WPF class, but a custom class created by Yourself:

public class DataItem
{
    public stringColumn1 { get; set; }
    public stringColumn2 { get; set; }
    public stringColumn3 { get; set; }   
    public stringColumn4 { get; set; }
}

To let the DataGrid display data stored in DataItem objects programmatically, You may do the following:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        // Your programmatically created DataGrid is attached to MainGrid here
        var dg = new DataGrid();
        this.MainGrid.Children.Add(dg);
        // create four columns here with same names as the DataItem's properties
        for (int i = 1; i <= 4; ++i)
        {
            var column = new DataGridTextColumn();
            column.Header = "Column" + i;
            column.Binding = new Binding("Column" + i);
            dg.Columns.Add(column);
        }
        // create and add two lines of fake data to be displayed, here
        dg.Items.Add(new DataItem { Column1 = "a.1", Column2 = "a.2", Column3 = "a.3", Column4 = "a.4" });
        dg.Items.Add(new DataItem { Column1 = "b.1", Column2 = "b.2", Column3 = "b.3", Column4 = "b.4" });
    }
}

I hope this helps.
