当服务器控件绑定到数据源时发生。
命名空间:System.Web.UI
程序集:System.Web(在 system.web.dll 中)
Public Event DataBinding As EventHandler
Dim instance As Control
Dim handler As EventHandler
AddHandler instance.DataBinding, handler
public event EventHandler DataBinding
public:
event EventHandler^ DataBinding {
void add (EventHandler^ value);
void remove (EventHandler^ value);
}
/** @event */
public void add_DataBinding (EventHandler value)
/** @event */
public void remove_DataBinding (EventHandler value)
JScript 支持使用事件,但不支持进行新的声明。
该事件通知服务器控件执行已为其编写的任何数据绑定逻辑。
