Label 能否成为焦点? [英] Could Label get a focus?

问题描述

I have a one question on my university's test about C#. Could label get a focus? As I can see on MSDN site, all Controls can get a focus, but some of them aren't selectable. So it's seems to me that the right answer is "Label could get a focus, but couldn't be selected". Also Label has a Focus() method. Please, help me understand. Thanx.

解决方案

Yes there is a Focus() method on Label and yes it is absolutely right it works; but behave differently. let me try to explain

A Label can be associated with some one input control, for instance a label for a user name text field, so there is concept of Associated Control with the label. AssociatedControlID on msdn

So you can associate an input control with a label and whenever label is selected the control passed to the associated input control.

Example here click on Email or Password labels in login box and see what happened, similarly if you call focus method on the label the focus will passed to the associated control.
