WinForms problem...

[Jacek Jurkowski]

I wrote my own WinForm controls inherited from
standard controls f.e. formatted TextBox etc...
All worked perfectly with Vs.net 2002 but when i
add my controls to a form visually with 2003 version
it's bahaviour is strange. F.e. I add my simple label control
to a form tab control. It looks ok but when i'm running the project
it disapperas. In the windows forms generated code i see
that this control wasn't addes to a tab control really. There is no
this.tabControl 0.Controls.Add( this.label0);
Control itself have no text property even if i set this before. There is no
this.label0.Tex t = "My text";
And the control size isn't set. There is some bug in WinForms generator?
Or I'm doing something wrong?

My control's code:

using System;
using System.Drawing;
using System.Collecti ons;
using System.Diagnost ics;
using System.Windows. Forms;
using System.Componen tModel;
namespace Datacomp.Dataco mpControls
