I have a project that has a form with a TabControl and lots of TabPages. There are too many tab pages to fit on the tab control, so it has a scroll arrow that allows you to scroll to the tab pages that do not fit.

There is a serious problem. The InitializeComponent() code generated by Form Designer keeps changing the order in which it adds the tab pages.


For example I start with

Code:
// InitializeCompnent
this.tabCtrl1.Controls.Add(tabPage1);
this.tabCtrl1.Controls.Add(tabPage2);
this.tabCtrl1.Controls.Add(tabPage3);
this.tabCtrl1.Controls.Add(tabPage4);
this.tabCtrl1.Controls.Add(tabPage5);
Then I add a button or something to one of the pages and I get

Code:
// InitializeCompnent
this.tabCtrl1.Controls.Add(tabPage3);
this.tabCtrl1.Controls.Add(tabPage1);
this.tabCtrl1.Controls.Add(tabPage2);
this.tabCtrl1.Controls.Add(tabPage5);
this.tabCtrl1.Controls.Add(tabPage4);
I have to keep changing it back to the correct order and everytime I edit the form in the designer, it rewrites InitializeComponent and puts the pages in the wrong order again. The ordering seems to be very random each time.

Is this a known bug in C#? If so, they better fix it in the next release of .NET.

Thanks in advance
