{
            _flex = new C1FlexGrid();
            _flex.Dock = DockStyle.Fill;
            this.Controls.Add(_flex);

            OleDbConnection con = new OleDbConnection("provider=microsoft.jet.oledb.4.0;Data Source=" + Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "\\ComponentOne Samples\\Common\\C1NWind.mdb");
            DataTable ordersTable = new DataTable();
            new OleDbDataAdapter("Select * from Orders", con).Fill(ordersTable);
            _flex.DataSource = ordersTable;

            _flex.GroupDescriptions = new GroupDescription[] { new GroupDescription("ShipCountry",null, true), new GroupDescription("ShipCity", System.ComponentModel.ListSortDirection.Ascending, true) };

            _flex.Tree.Column = 1;
            _flex.Tree.HandleInvisibleChildren = true;
            _flex.Tree.Indent = 30;
            _flex.Tree.LineColor = System.Drawing.Color.Blue;
            _flex.Tree.LineStyle = System.Drawing.Drawing2D.DashStyle.DashDotDot;
            _flex.Tree.NodeImageCollapsed = Properties.Resources.expand;
            _flex.Tree.NodeImageExpanded = Properties.Resources.collapse;
            _flex.Tree.Style = TreeStyleFlags.SimpleLeaf;
            _flex.Tree.Show(0);
