In the program I am developing it was necessary to create a control that has
a textbox inside it. When I put, for example, three instances of my control
on a form, set the tab order (or tabindex property) for each of them and run
the application, the controls dont work as expected when I press the tab
key to move between them: if, with a mouse click (over the text box inside
the control...) I select the first control and then press the tab key, it
goes to the second control, as expected, but then, if I reselect the first
control with a mouse click over the text box inside it and press the tab
key, the focus goes to the third control, as if the second control still had
the focus... if I, again, reselect the first control with a mouse click and
press the tab key, the focus will continue in it (as if the third control
still had the focus and the first was being focused...)

I noticed this only happens if I put the text box inside the control I
create (opposed to inheriting from the TextBox class), as if I needed to do
something else to tell the parent control that a child control of it got the
focus so that the parent control updates its info about which control is the
active one (has the focus).

I dont know if I was clear enough explaining the situation. If not, please
just say it and I will try to clarify.

Thanks for your attention,
Daniel Cardoso

Let me know!
