public class CustomPanel : System.Windows.Forms.Panel

{

    protected override System.Drawing.Point ScrollToControl(System.Windows.Forms.Control activeControl)

    {

        // Returning the current location prevents the panel from

        // scrolling to the active control when the panel loses and regains focus

        return this.DisplayRectangle.Location;

    }

}
