推荐答案

是有上标注焦点（）方法是的，它是它的工作原理完全正确的;但不同的表现。让我尝试解释

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

标签可以用一些一个输入控件关联，例如一个用户名文本字段标签，所以相关联的控制与标签的概念。 <一href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.label.associatedcontrolid.aspx"相对=nofollow> AssociatedControlID MSDN上

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

所以，你可以用一个标签输入控件关联，每当标签被选中传递给相关的输入控件。

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

例这里在登录框中单击电子邮件或密码标签，看看发生了什么，同样，如果你调用对焦方式标签上的焦点将传递给相关联的控制。

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.
