Like the other posters have commented, you're required to roll your own. Luckily, this isn't too difficult.

In my application, I needed a way to draw a 16x16 icon in a particular column. I created a new class that inherits from DataGridColumnStyle, which makes it easy to apply to a DataGrid via a DataGridTableStyle object.

class DataGridIconColumn : DataGridColumnStyle {

public Icon ColumnIcon {
    get;
    set;
}

protected override void Paint( Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight ) {

    // Fill in background color
    g.FillRectangle( backBrush, bounds );

    // Draw the appropriate icon
    if (this.ColumnIcon != null) {
        g.DrawIcon( this.ColumnIcon, bounds.X, bounds.Y );
    }
  }
}

You can see that I defined the public property ColumnIcon so I can specify the icon I need to display outside of this class.

Now, to actually use it on a DataGrid, you'd have a snippet like:

DataGridTableStyle ts = new DataGridTableStyle();

DataGridIconColumn dgic = new DataGridIconColumn();
dgic.ColumnIcon = Properties.Resources.MyIcon;
dgic.MappingName = "<your_column_name>";
dgic.HeaderText = "<your_column_header>";

ts.GridColumnStyles.Add(dgic);

this.myDataGrid.TableStyles.Add( ts );

That's a pretty simple example for applying the DataGridTableStyle -- I actually do a lot of further customization on the rest of my DataGrid columns. But it should get you started on what you want to do.
