event handler delegates

基本解释

Registers beginning and ending event handler delegates for an asynchronous page.
爲非同步頁麪，注冊開始與結束事件処理常式委派。
Registers beginning and ending event handler delegates that do not require state information for an asynchronous page.
爲非同步頁麪，注冊不需要狀態資訊的開始與結束事件処理常式委派。
The binding mechanism used with delegates is dynamic: a delegate can be bound at run time to any method whose signature matches that of the event handler.
使用委托的綁定機制是動態的：委托可在運行時綁定到簽名與事件処理程序的簽名相匹配的任何方法上。
