CN1.NextControl.VISIBLE CN1.NextControl.ENABLED CN1.NextControl.TABSTOP CN1.ENABLED CN1.NextControl.When() ....>I expected the behaviour to be that I could not tab to the container control but once a control in the container had focus I should be able to tab to the next control in the same container. If I wanted to prevent this behaviour I could set the TabStop property to false for each of the controls in the container.
