DataGridTableStyle.MappingNameChanged 事件
在 MappingName 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 MappingNameChanged As EventHandler
用法
Dim instance As DataGridTableStyle
Dim handler As EventHandler
AddHandler instance.MappingNameChanged, handler
public event EventHandler MappingNameChanged
public:
event EventHandler^ MappingNameChanged {
void add (EventHandler^ value);
void remove (EventHandler^ value);
}
/** @event */
public void add_MappingNameChanged (EventHandler value)
/** @event */
public void remove_MappingNameChanged (EventHandler value)
JScript 支持使用事件，但不支持进行新的声明。
备注
有关处理事件的更多信息，请参见 使用事件。
