爲什麼我的addhandler不能正常工作？AddHandler無法正常工作
在Sub「CreateTagStyle」中，單擊LinkButton時，AddHandler不會觸發。在頁面生命週期的某些時間點，添加處理程序不能添加是否有某些原因？

是啊，這是有道理的。我在這個Sub中使用了DataItem，所以我不認爲我可以在ItemCreated中這樣做，所以我只需要爲該部分找到解決方法。 – EdenMachine 2010-04-26 13:43:22
嗯 - 基於你非常有用的鏈接，它看起來像我需要分裂一點。在ItemCreated中添加處理程序，並以某種方式完成ItemDataBound中的所有數據工作。希望我能做到這一點。謝謝你的幫助！ – EdenMachine 2010-04-26 15:41:38
