Question:
When tabbing through the controls on a form, a radio group
requires two tab keystrokes if an item is selected, but only
one if no item is selected. Since two tab keystrokes are
required in this case one of the tab keystrokes gives no
visual indication that the focused control is the RadioGroup.
Is there any way to make the behavior more consistent?
Answer:
Setting the TabStop property of the RadioGroup to false should
correct the problem, yet still allow the tab key to function,
so long as one item is selected in the RadioGroup.
