DataGridColumnStyle.AlignmentChanged 事件

在 Alignment 属性值更改时发生。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Event AlignmentChanged As EventHandler
用法
Dim instance As DataGridColumnStyle
Dim handler As EventHandler

AddHandler instance.AlignmentChanged, handler

public event EventHandler AlignmentChanged

public:
event EventHandler^ AlignmentChanged {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}

/** @event */
public void add_AlignmentChanged (EventHandler value)

/** @event */
public void remove_AlignmentChanged (EventHandler value)

JScript 支持使用事件，但不支持进行新的声明。
