TabPage page = new TabPage ( ); page.AutoScroll = true ; Button btn = new Button ( ); btn.Text = Add label ; btn.Click += delegate { Label lbl = new Label ( ); lbl.Location = new Point ( 0 100 ); lbl.Anchor = AnchorStyles .Left; lbl.AutoSize = false ; lbl.Width = this .Width + 400; lbl.BackColor = Color .Red; lbl.TextAlign = ContentAlignment .MiddleCenter; lbl.Text = centered text ; page.Controls.Add( lbl ); if ( lbl.Width > page.Width ) { page.AutoScroll = false ; page.HorizontalScroll.Value = ( page.HorizontalScroll.Maximum - page.HorizontalScroll.LargeChange ) / 2; page.AutoScroll = true ; } btn.Dispose( ); }; TabControl tabCtrl = new TabControl ( ); tabCtrl.Dock = DockStyle .Fill; tabCtrl.TabPages.Add( page ); this .Controls.Add( btn ); this .Controls.Add( tabCtrl );
