Preserving Focus on a Control in a TabControl in VB.NET

[samadams_2006]

Hello,

I have a VB.NET Form which has a System.Windows.Forms.TabControl on it.
This TabControl has 5 Tabs on it. On each tab, I have various
textboxes, option boxes, radio boxes, etc. I would like to have the
ability to save the focus on a particular control, so that when I go to
another tab, then back to the same tab, the control I left will still
be the highlighted control. For example, if I'm on the "City" Textbox
on the "Customer" Tab, then go to the "Orders" Tab, then back to the
"Customer" Tab...I would like the "City" Textbox to have the cursor on
it. I need to do this without affecting the "TabOrder" of the
TabControl. I've looked into "Focus", "Select", "ActiveControl",
etc...but nothing seems to work.

Any ideas?

Thanks.
