2.3 Why do calling Focus() on a control not set focus on it? |
| Note that when you call this method the control should be visible, otherwise the focus will not be set. Hence calling this in say Form_Load on a control in the form will be ineffective. You should instead consider give that control an appropriate TabIndex, so that it will be the first focused control. |
