All you need is to use a DoubleBuffered DataGridview subclass:

class DBDataGridView : DataGridView
{
    public DBDataGridView() { DoubleBuffered = true; }
}

It is also possible to inject double-buffering into a normal out-of-the-box control, but I prefer to have a class of my own as this is extensible in other ways as well..

I have expanded the class by a public property to allow turning DoubleBuffering on and off..:

public class DBDataGridView : DataGridView
{
    public new bool DoubleBuffered
    {
        get { return base.DoubleBuffered; }
        set { base.DoubleBuffered = value; }
    }

    public DBDataGridView()
    {
        DoubleBuffered = true;
    }
}

..and tested it with a load of 200 columns and 2000 rows. The difference is obvious; while vertical scrolling did work without horizontal scrolling needs DoubleBuffering..

Note that the Form also has a DoubleBuffering property, but that will not propagate to any embedded controls!

Or you can use a function like this
